Doing a release WebGL build with 2019.1.2f1 crashes my entire computer

I'm trying to do a WebGL build using 2019.1.2f1. I can do a Development build, but twice now I've tried a Release build and it gets towards the end and my Windows 10 PC just freezes. The mouse pointer stops moving, I can't Ctrl-Alt-Delete or Ctrl-Shift-Esc or anything. Have to do a hard power-off.

Any ideas why this might be happening, or is there any way I can turn on some kind of diagnostics or logging to help diagnose the issue?

The project is just a hobby, so I don't mind sharing the source code if that would help.

Thanks,
Mark

 

Right, I did a couple of things and I'm not sure which of them fixed this, but I fixed it:

• Deleted the Library and Temp folders, which I'd copied over when I upgrade the game from 2018.3
• Excluded the Temp and build output folders from Backblaze
• Excluded the entire Unity folder where my projects live from Windows Defender anti-virus scanning

Sorry for not doing a more scientific test, but like I say, it was hanging my whole PC and that worried me.

 

Just FYI, I just came accross your post because I was having the same issue as you, and your solution helped me.
I was actually getting BSOD when building Webgl and not sure if removing the folders or adding the windows defender exception helped, but I was just able to build it finally without crashing, so a huge thank you!

 

Thank you!

I also don't know which of the 3 did it...but I was able to build after struggling on and off with crashes for months!!!
