System Information
Operating system: Linux-5.3.0-46-generic-x86_64-with-debian-buster-sid 64 Bits (linux Mint 19.2)
Graphics card: Mesa DRI Intel(R) UHD Graphics 630 (Coffeelake 3x8 GT2) Intel Open Source Technology Center 4.5 (Core Profile) Mesa 19.2.8

Blender Version
Broken: version: 2.83 (sub 15), branch: master, commit date: 2020-04-29 08:26, hash: 839fe335d2
Worked: unknown

Short description of error
Blender freezes when accessing the System tab on the Preferences window

Exact steps for others to reproduce the error
Open Blender, go to Edit > Preferences > System

The problem appeared after installing Intel opencl Neo ISD package and disappear when I remove the package.

This might be linked to blender/blender-addons#73024

I found the problem initially on 2.82

Best regards,
Stephane

Can you attach the output of running clinfo on the command line?

Can you attach the output of running `clinfo` on the command line?

Ok, this is a duplicate of #68052 (Segfault when accessing Cycles Render Devices preferences with two OpenCL platforms, AMD Mesa Clover and Intel Gen9 NEO) I believe.

So far I've been unable to reproduce this or figure out why exactly it happens, due to not having this hardware.
