System Information
Operating system: Windows 10
Graphics card: Nvidia RTX 2060

Blender Version
Broken: 2.93.0-b5d154f400e4
Worked: 2.93.0-461d4fc1aae2

Caused by a3f091d7ce

Short description of error
Crash while enabling boolean modifier with exact operation. File is a part of a model I narrowed out for this report.
Mostly sure the model's mesh is easily fixable to prevent the crash, however i thought it could be useful to post it in here.

(May or may not be related to a fix implemented due to my previous bug report on booleans)

Exact steps for others to reproduce the error
Open the file, select the main model and enable the boolean modifier, blender should crash after that...

Yeah, it is caused by a3f091d7ce

problem seems to be when mesh with modifier has custom split normals (unnamed layer) and boolean object hasnt.
