out of memory

In the last few days when using Figma, the browser frequently crashes, prompting out of memory, which was rarely encountered before last week, and the Figma file itself has not undergone any major changes, so I don’t know what’s the reason.
Computer memory: 16g

Hey @zhurui644834655 ,
Thanks for reaching out to the community, and sorry for the trouble!
Figma is browser-based, and every browser has its own active memory limit of ~2GB per browser tab.
As a workaround, for instance if you break your file down into multiple smaller files, the performance of Figma will improve significantly.
