System Information
Operating system: Darwin-19.5.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon R9 M395X OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.9.15

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-07-04 15:31, hash: 464aaf2701
Worked: 2.83.0 , caused by afd976a3b4 ?

Short description of error
When the view port has both the object modelling window and the UV Editor window open, Blender crashes when entering edit mode. I repeated the crash several times in a row. It would crash when trying to edit several different meshes. Once I closed the UV Editor, the crashing stopped.

Seems similar to https://developer.blender.org/T70247 but the problem manifests in 2.90 Alpha and not in 2.83.0. Also, I think it started to manifest around the July 1 build.

Exact steps for others to reproduce the error
Select a mesh and enter edit mode based on sample .blend file.

No crash here (tested on 4f3045999d).
Textures are missing though, could you reupload the file with packed textures?

I believe there was an issue with normal maps (I think that was fixed though), but

could you also try the newest build from https://builder.blender.org/download/?
remove the normal map node in the shader and see if it still crashes?

I've downloaded and tried the July 5 build, and the crash still happens.
I've also tried removing the Normal map, and the crash still happens.
I'm uploading a version with the textures packed.

I don’t have the hardware and therefore cannot bisect this issue, but if I were to guess the cause, I would go with the July 1st UV editor commit that affects only MacOS afd976a3b4

CC @fclem : does this ring a bell (also cannot really confirm - not on MAC)?
