How many backups did you take before and after the incident? Why not just restore one of them?
It’s probably easier if you took an additional backup and then just re-installed Mint without deleting the previously available data. This way you can get back easily what you have lost.
Still, it would be best to just restore one of the many backups you created.

Well, that’s your problem. I have no idea how you could do all these things without a single backup.
You should start from scratch and this time take regular backups.
i have set chroot environmen by “Chroot into a btrfs uefi system from live media - #3 by xircon - General system - EndeavourOS” but my ubuntu mate is not showing in grub i tried sudo update-grub and installing grub again but don’t work .
