Can't start Unity 5.5b1

Hi,
when I try to start Unity 5.5b1 without launched it from a project (so by clicking on the d esktop icon for example). The project choice window is just grey and nothing happen.

I can't fill a bug in the engine cause it won't start. This is how it looks :



When I tried to start a project with unity 5.5b1 directly from a scene file this is the window (after the switching process from my previous unity version to unity 5.5b1) :



As you can see it's not really the same issue (I mean in the window display) cause there is nothing write in the window header (unity 5.5b1) and in the windows task bar in my desktop, there is nothing (no icon) in the second case.

Last test, if I click on the same scene after the previous import switching just nothing happen. Windows don't event try to start unity editor.

I work with Windows 10 64bits Pro.

 

As soon as I go back home (so tonight) I will post the "Editor.log" I totally forget to past it in my post.
I just tried at the office and nothing goes wrong with the beta :'(

Looks like a bug loading the project browser

Not sure if clearing the node cache might help, but will ask the project browser team to come take a look.

 

Apparently, 5.5.0b1 starts only if there is already another version of Unity installed. I wanted to do a clean install, so I removed all the Unity directories in AppData and ProgramData; all I get is the window the op has posted. Once I put back the Unity directories I had deleted, Unity 5.5.0b1 started normally. I hope my experience will help.

 

in this folder there is only a file named "package.json" with this in :

 

Hope this issue will be fixed in next update

 

Unfortunately, to get keep the cycles short, unless it's reported really early, the minimum latency to fix is usually 2 builds (usually 2 weeks).

Keep watch on the release notes!

 

Install another version Unity 5.4, launch it so that the directories are created in the AppData and ProgramData folders and then install 5.5.

 

I was having the same issue. Empty UI went back and installed an earlier version and now 5.5 Beta works like AnneSchmidt mentioned.
