Thanks for report,

I see that crash occurs inside GPU driver.

Please Make sure your OS and libraries is up to date and check if this problem happens wiht latest builds from https://builder.blender.org/download/

I am running the latest Ubuntu LTS (20.04.1) and have tried installing and running blender before and after upgrading my system with similar results.
The same problem happens also with the newest 2.91 Beta available from the website (2.91.0 Beta, 2020-11-12, b99faa0f56). The crash report is very similar:
blender.crash.txt
The same happens also with 2.92.0 Alpha, 2020-11-12, 2ef2b3e0fd00:
blender.crash.txt
Both of them give the same output to the terminal also.

I remembered in report #77466 after Blender crashed, you would see following log in dmesg:

Can you run dmesg in console and check if you see something similar and paste that section here?

Running dmesg gave nothing similar to that. I can also include a file of the whole output if needed.

Please add as much relevant information as you can. So at least we know this isn't same issue, but unfortunately I can't tell what the problem is here.

Sorry for the delay. I am not very experienced in this kind of task, so I don't really know what information is relevant. What kind of information should I post here?

I was just responding to your previous comment, if you should include dmesg output.

This report has been unconfirmed for 1 year so far.

Realistically, not much we can do here apart from suggesting checking on a newer drivers.
While this is a real issue, it is only happening to a few people so far. And to troubleshoot it developers needs to have direct access to hardware. And even then it is not clear whether it's a solvable problem from Blender side...
So thanks for the report, but doesn't currently looking like we can solve this driver issue :(

To upgrade to the latest driver, see here for more information: https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html
