Build crashes with: "...resources.assets' is corrupted! Remove it and launch unity again!"

[manuelgoellnitz]

I Updated from 2020.1.16 to 2020.2.1.
When I now create a build and run it, it immediately crashes.
in the player log is the message:

…/resources.assets’ is corrupted! Remove it and launch unity again! [Position out of bounds!]

This happens also if I create the build with another PC. So the file is created “corrupt” during build.

When I downgrade to 2020.1.16 the builds are created correctly.

Can anyone tell me what causes that error?
Is there a way to analyse that file?

I found the cause of the problem in my project

I posted it in the UIToolkit Forum, since it is related to that package:

TextMeshPro Files can cause currupted builds with Unity 2020.2.1

Since the latest UIToolKit-Version TextMeshPro is integrated. In Resources-Folders some Files are created. If you have the resource files which the old TextMeshPro System created are still present in your project, it causes build created with Unity 2020.2.1 to crash. Probably because then there are two asset Files with the same name present. After I deleted the old asset Files which are in both systems, builds worked again! Unity 2020.1. did not have that problem.
