Standalone hvm import with 0.0mib

Hey everyone.
If i want to import my windows hvm on another pc it imports with 0.0mib, but the disk is 60Gib.
I also have the problem of importing qubes with firefox, all the data is gone, if i import it on another pc. the weird thing is if i export and import it on the same pc it all works.
Please help

Kind regards

you was using the Qubes backup function? I always had luck with qubes backup - can move my Windows11 from Qubes device to another.

yes, i did use the backup and restore function. But it doesn’t work on different pc’s…
