I have a source built version of Unreal Engine. Up until today I was using the version from the release branch. I got a crash on it and updated to the latest commit on the 4.26 branch to see if it would fix the issue, which it did not.
If I select a particular mesh, and then go into texture painting, the editor immediately crashes. I don’t even have to click the button, just hovering the mouse over the “paint” button causes it to crash.
The error message tells me nothing and it repeats forever until the editor closes.
This doesn’t happen with every mesh either (but it does happen with the one I need, of course).
Exception thrown at 0x00007FFAE3FF319C (UE4Editor-MeshPaintingToolset.dll) in UE4Editor-Win64-DebugGame.exe: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x0000005E74203FB4).

Any help is appreciated.
