Crashed file lost my job

Nobody is working support of this thing because ive been reporting bugs all day, so lets see if a nice citizen can help me out on this.
I tried to restore an older version of a file and it has broken Figma. It wasnt even a version from long ago, just yesterdays. I now have lost a full day of work and a whole bunch of money. This file is WEEKS worth of work and it is just stuck in the Figma loader with every single button and link disabled and not even a preview of the file.
Since i don´t think anyone from Figma is going to help me with this because ive been trying to contact support for 12 hours, and now ive lost a project, a customer, my payment, etc etc, if anyone has any advice on suing this company, that is very welcome as well.
