I see there may be a related behavior related to plug-ins.
In my case, whenever I right-clicked an element for the context menu, the screen would go blank. Figma didn’t crash, but the screen would blank. Closing the project and re-opening restored the screen but the behavior would repeat. This happed on the Web and desktop versions. I wasn’t actively using the plug-in manager or any particular plug in when this happened. Eventually after a few reboots and updating the desktop app, the issue resolved, but it was very disconcerting.
