Now the file doesn’t even open any more, not even after I restart Figma.

Hi there! Sorry to hear this is happening.

In order to restore previous version, please make sure to follow these steps in our guide: here.

Figma is a browser-based app, which means it’s subjected to a 2GB available memory limit that applies to each browser tab, including those in our mobile app, or mobile browser. When loading or editing Figma files nears or exceeds this memory limit, it can cause performance issues like long load times or crashes. I’d recommend you first taking a look at our guide on how to Reduce memory usage in files.

If this still doesn’t help, please reach out directly to the support team with a copy of your file so they can investigate it further here.

Be sure to use your Figma email account, include a link to the file and share it to support-share@figma.com as an Editor to this file (this won’t affect your billing at all). Thank you!
