Hey Rafael! Welcome to the community and sorry to hear this is happening with your prototype.
Usually, you may run into these limits when you’re working with large files and libraries in Figma.
For your information, every browser has its own active memory limit. This can differ across devices but the general understanding is there’s an active memory limit of 2GB for each tab in a browser.
To continue to use affected files, you will need to reduce your memory usage. This can involve splitting up large files, removing hidden layers, or reducing large assets.
As a first troubleshooting, you can find some tips in our article to reduce memory usage in files: here
If this still doesn’t help, I’d suggest you to reach out directly to the support team with a copy of your file so we can investigate further the root cause, by filling this form: here
Be sure to use your Figma account email, include a link to the file, and share it with support-share@figma.com.
Hope it helps!
