There is some kind of regression with this driver causing kernel memory corruption. This can cause crashes, hard freezes, or other issues. There is a related discussion in this thread here if you would like to take a look:
There don’t seem to be any super great options for dealing with this right now. You can downgrade the driver and associated packages, which may require switching kernels as well, or scrap the drivers altogether and run Nouveau for a while. Have a read through that thread and see what you think.
