Server backup for project page

Good day. I have a problem. I selected all the assets on the project page and deleted them. When I clicked  "Undo" Figma crashed, citing insufficient memory (64GB of DDR5 is apparently not enough).
Could you please, if possible, restore the page to the state it was in before the deletion? Perhaps using a server backup or something similar? Or could you suggest where I can turn to with this problem? If I need to subscribe to something or do anything else – that's not a problem, just please help me with the assets.
Thanks in advance.
