Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00
Broken: version: 2.90.0, branch: master, commit date: 2020-08-31 11:26, hash: rB0330d1af29c0
Worked: (newest version of Blender that worked as expected)
Short description of error
Sometimes when I close the Render pop up windows(F12) it will do a full close of Blender (Not being asked to save etc)
Exact steps for others to reproduce the error
I don't have found an exact way to reproduce but usually happen after +30-60 minutes in Blender and done a few renders. This happens to me almost every session.
