Cannot restore deleted data

I accidentally deleted some files (~40GB) from my nextcloud. I know that nextcloud has an feature to restore data, but it doesn’t work. If I navigate to the site where i can restore my the only thing you can see is a spinning circle (the site had over 1 hour time to load in the background). I’m sure the data still exists, because i can find it in the file manager but i cannot restore it.
Is there an alternative way to restore data?

did you look in nextcloud/data/<user>/files_trashbin/files ?

before you do anything. make a backup. :wink:
