I couldn’t find any similar issue reported. So this is my first post ever 
I’m on 2019 LTS & Windows 10
My editor is freezing when it should change the scene in game mode.
When I build the project for Windows it is freezing at the same situation.
However, when I build for Android it is running fine on my mobile.
Now it starts getting difficult:
My friend can run the same project on his PC without any issue.
Also the windows player built on my PC is running fine on his PC.
I have entirely re-installed Unity, Unity Hub including clean-up of registry and cache.
Visual Studio was also re-installed.
I have no more ideas other than re-installing Windows, which for sure would be painful…
Anyone who have an idea or had similar issues?
maybe is graphic card driver. try updating it, see if it works
Thank you dorusoftware, so long as I don’t need to go for re-installing Windows, I’ll give everything a try…
Graphic card driver updated, unfortunately no change.
One thing I wanted to add:
I have the issue only with one project.
In other projects the Editor is not freezing.
Could you capture a dump file (by finding the stuck process in the task manager details tab, right clicking on it and pressing “Capture Dump File”) and send it to me after compressing it to a zip/7z file?
What is the CPU usage of the process when it freezes?
My Editor is working again
I didn’t changed anything in Unity, but used the Windows repair tools: SFC (System File Check) & DISM (Deployment Image Servicing and Management).
SFC repaired some files, but I still had the freezing issue.
Today I went for a second run of SFC and in addition also DISM, both tools reported that nothing was repaired, but now all is running (faster than ever) again…
