Hello @Irshad

According to different source there is actually a limit of how much RAM can be allocated per tab in chrome (which seems to be 16GB according to thissource, the same source postulated that you can go twice as much in Firefox).

You may also try to download the application, even though it’s an electron app, it might be able to go further.

Last but not least, you can take a look at the memory usage (Figma button > View > Memory usage) and try to split your file in multiple smaller one.
