If this doesn't help, goto NVidia's site. there’s a new version of the Studio driver available. Download and do a clean install of the driver. Then check.

If this also doesn’t help try to create a new catalogand import several images and check if it’s work.

In case of success you can import the images from the old catalog to the new one.

Try to disable third party plugins in Lightroom. Perhaps there’s a conflict.

It could also be a Windows issue or a hardware problem:

• Check if you have enough free disk space and check also the size of the virtual memory paging file .
• Check for faulty RAM. Run a memory diagnostic tools to check for hardware issues. 
• Reset or reinstall the printer driver.
