After update version to 15.1.1 in Jan 2026,  constantly experienced system crashed after opening LRC.

System crashes (meaning the whole computer stops working and has to be re-started) are caused by out-of-date/corrupted drivers, or hardware malfunctions.

Tried to disable the GPU processor and update the NVIDIA driver to the latest version, even reinstalled LRC again, unable to resolve this issue. 

Did you successfully install the latest NVIDIA Studio driver? You don’t tell us, you just said you tried. What version NUMBER is it? (We need version NUMBER and not words like “latest”) Also, installing a Game-Ready driver will not necessarily be helpful.

Please go to Help->System Info and provide us the information that appears there.
