@Hubert Piątkowski (Bobo) , thanks for the information. So many add-ons are enabled which I can see in system-info.txt.

Please try again with factory settings (File -> Defaults -> Load Factory Settings) ?

I can't test it in default. I work full time and it can slow my workflow. I disable half of addons( left mostly import-export) and problem did not desapear.

Blender freezes when scrolling using middle mouse button. Releasing MMB while moving is more likely to crash it. It happens with 2.83 LT and 2.93 LT. Mostly using 2.93.
Have to use task manager to force quit blender.
Windows 10 on MS Surface Pro 7, quad core i7. 16GB ram.

Some 3rd party add-ons are also enabled but could not blame them without much information.

So far I am not able to reproduce the issue.

Please check if your graphics driver is also up-to-date otherwise to update them, refer: https://docs.blender.org/manual/en/latest/troubleshooting/gpu/index.html#windows

Graphic drivers was the first thing I checked, for both cards. I believe that Blender crash only or mostly when runs on integrated Intel HD Graphics 530.

Most of this third party add ons only runs python commands that are assigned to interface buttons.

I think we really need to test this once with complete Factory Defaults.
(no need to worry about loosing defaults, all will be back to usual if you restart blender).

So please try with File → Defaults → Load Factory Settings to see if you still can reproduce this issue.

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.

Thanks again for the report. If the problem persists please open a new report with the required information.

It is not closed. It still happens with clean install no Add-ons

Thanks for checking. Report was closed because no reply was received within a week (As said in the Triaging Playbook)

Could you please add the log files?: https://docs.blender.org/manual/en/latest/troubleshooting/crash.html#crash-log

Does this only happen with the file which you have provided or is this something you can reproduce with every file?

Also, can you recreate the issue with any other blender version? (eg. 3.0.0, 2.92, 2.83)

May be this is expected. see: https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html#why-is-blender-unresponsive-during-rendering

While a graphics card is rendering, it cannot redraw the user interface, which makes Blender unresponsive

I think this appears for the first time only. Did you wait till the end of compilation of the kernel?
