I share an Unreal Engine (4.26) game with a (non-technical) colleague through Git. Today he received his first code files from me, and to compile it, I had him install the SDKs(windows, .Net, C++ gaming, Visual Studio) and call Generate Visual Studio Project Files. It all generated just fine.
But when the time to start the Engine came, it crashed with this:
EDIT: After emptying the Recycle Bin, the error is the same, but the file different.
ERROR: Unhandled exception: System.UnauthorizedAccessException: Access to the path ‘D:\System Volume Information’ is denied.
Since this looks like a permissions problem, I tried having him run the engine as administrator, tick off all the read-only in Properties->General for Epic Games and UE, and enable developer mode, nothing seems to do it. I don’t really see how much more permissions I can get than that.
Former error:
ERROR: Unhandled exception: System.UnauthorizedAccessException: Access to the path ‘D:$RECYCLE.BIN\S-1-5-18’ is denied.

We have tried a few things, like generating again, or copypasting all of our assets to a new project: if we copy the assets, all good, if we copy the code, the same crash.
This happens only on his machine, so I’m kind of at a loss for words. He did not delete any files, the only difference between his machine and mine is that his SDK is more up-to-date by a few weeks.
I’d really appreciate any clue regarding why this file comes up in the build or how to stop it from crashing. The C++ code doesn’t seem to be the issue at all, and he can’t start Unreal Engine anymore.
