Lightroom Classic Freezes computer

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

A couple of thoughts:

1. Obtain the most recent graphics driver from the manufacturer (not via Windows update) and do a clean installation:

Even though you've got the GPU off for LR, it's possible that bugs in the core graphics driver are getting triggered by LR.

2. When you say "freeze", does the screen go black or Windows blue screen of death, indicating that Windows itself has crashed?  Or does the screen really freeze, showing you the contents of open windows, etc. but the computer just stops responding to the mouse and keyboard?  If Windows is crashing (screen going black or blue), then it could be your cooling fans are clogged and not working properly.  LR uses much more of your computer's CPU than most apps and can easily cause a computer to overheat if its cooling system isn't working properly, in which case the computer shuts down abruptly.
