playmode crash without any info, when there is no access to the internet.

when I pressd the play button, once there is no internet, the editor would crash, and no error window shows. I go to the log folder to find the editor log, and the last line is :
* Assertion at ..\mono\metadata\threads.c:1788, condition `internal` not met.
I tried to reinstall the unity3d 2019 2.11f,and useless. I created a new project, and still crash when there is no internet.

and if build the project, the exe file is working fine.

 

I have the same issue. In conversations with the Unity QA team, will let you know what they say...

 

I also have this issue, it happens in Unity 2019.2.11f and 2019.2.12f, other versions have not been tested.

Edit:
After uninstalling Unity, deleting every file from Unity and installing it again it works now.
I followed this instruction for macOS:
https://forum.unity.com/threads/uninstalling-unity-on-mac.395154/

 

Are there any news regarding this issue? Unity keeps crashing on me...

 

I see this too in Unity 2019.2.12 on Windows. Has anyone posted an official bug report?

 

No, still crash when no Internet.

 

Just a quick note to say that the Unity support team got in touch with me today to say that:
"I have forwarded the issue to the developers responsible for this area and I will let you know any findings as soon as possible".

I'll post back here once I hear back from them.

 

Quickly updating that I heard back from Unity, and they say the issue should be fixed in the next release of the 2019.2 stream.

 

I just got this issue today and it's been a wild ride trying to get to the bottom of it. I think it's occurring from a Resources.LoadAll call because I managed to trip across a line that, if commented out, gets the play function to work but the game comes up paused so it's not 100% good. Plus... I sorta heavily rely on that loadall call so I can't think of a workaround yet.

You mention that not having internet is the cause, but I am connected to the internet. However, I saw this error earlier today before the play-button crashes began:

error:00000000:lib(0):func(0):reason(0)Curl error 35: Handshake did not perform verification. UnityTls error code: 7

I wonder if anyone else has that with this crash.

 

Yup, just had this happen today. I get:

error:00000000:lib(0):func(0):reason(0)Curl error 35: Handshake did not perform verification. UnityTls error code: 7

(Filename: C:\buildslave\unity\build\Modules/UnityWebRequest/Implementations/TransportCurl.cpp Line: 734)

* Assertion at ..\mono\metadata\threads.c:1788, condition `internal' not met

I'm not using Resources.LoadAll, but I am using Resources.Load in various places (and I'm connected to the Internet) so it could be similar. The weird thing is everything was working fine last night, and then without making any changes it started crashing today.

I tried a complete clean install of Unity (deleted every version I had, preferences, the Hub, etc.) and tried on both 2019.2.12 and 2019.2.14 but still got the error. Hoping it really does get fixed with the next release.

 

Same here. Worked fine last night. Zero changes made. Run Unity this morning and this S*** starts happening. I've actually had Unity run by commenting out the Resource Load calls, then uncommenting them, which is just... really stupidly broken... the issue then occurs in a coroutine call which causes the crash... then the crash keeps happening after commenting THAT call out while ALSO commenting out the resource load calls. It's freaking WILD how broken Unity got today!

My project works fine on another computer. I'm too scared to completely clean Unity off considering this should be fixed in the next release.

How often does Unity release because I need this work done by uhhh next week and I'd very much like to not have to develop on my second machine.

 

Looking at the release dates, usually within a week or two (and it's already been like 6 days since the last one so possibly very soon).

 

Same issue. First I get crash when was offline, now it crashes every time even with Internet connection.

 

Same issue. Tested offline start with Unity 2019.2.12f1.

Also detected problems with UnityWebRequest timeout property and Abort - https://forum.unity.com/threads/iap-crashes-unity-with-unitytls-error-code-7-in.787847/#post-5244035

 

From the thread linked to by wicea:

Editor is now playing for me!

 

To those interested in an update on the original issue (editor crashing when there's no internet connectivity), the latest from the Unity support team is that they expect it fixed in 2019.2.16f1.

 

Me too. I'm using PlayFab API and Unity will crash if no internet connection. I expected Unity to throw an exception but it crashed.

 

Me too
Assertion at ..\mono\metadata\threads.c:1788, condition `internal' not met

 

Hi, same here.
Editor 2019.2.13f1 crashes without any warning, anytime I try to access an invalid url on a UnityWebRequest or even through a Playfab API request.

(Filename: C:\buildslave\unity\build\Modules/UnityWebRequest/Implementations/TransportCurl.cpp Line: 734)
* Assertion at ..\mono\metadata\threads.c:1788, condition `internal' not met

 

Same here (2019.2.11f1)

 

without internet it started but after connecting net the unity crashed can anyone help me. sorry for bad english

 

Unchek this

 

Experiencing the same thing. Silent crash on hitting play no message or anything. Checking the log, the last thing I see is:

Code (CSharp):

1. (Filename: C:\buildslave\unity\build\Modules/UnityWebRequest/Implementations/TransportCurl.cpp Line: 734)
2.  
3. * Assertion at ..\mono\metadata\threads.c:1788, condition `internal' not met

Weird that this causes a crash on play, but this fixed it for me. I'd prefer to run it with that checked, but I guess that's not an option anymore.

 

Not fixed as of 2019.2.18f1. Crashes randomly during play mode in a very simple build, and there is no pattern that I can find.

 

This fixed it for me too, I am using unity2019.2.13f1. thanks!

 

• Replace with another disk and reinstall
  

 

I just had the same problem with version 2018.4.26f1. This time there is Internet, but there's an error: Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED. This is followed by: Assertion at ..\mono\metadata\threads.c:1788, condition `internal' not met.

The "Fix" is the same - turn off Error Pause

 

That did the job.

 

I spent all night searching for why Unity 2019 crashes on play [SOLVED].

Unity Editor 2019.5.17f1 was crashing every time I press played (repeating for SEO so other people can find it and not waste a whole night )

I can confirm, unchecking "Error Pause" fixed it for me.
