I have been working with Tumbleweed in a VirtualBox VM since Corona forced us
all into home office, and it had always worked fine to use a shared folder from
my host system for software development.
I even wrote up the procedure how to get this working, and that's what I did
(and verified):
https://github.com/shundhammer/huha-linux-tips/blob/master/doc/virtualbox-tips.md#sharing-folders-between-host-and-guest-system
But this stopped working since I got back to work with that VM today after a TW
update: Everything in my shared folders is now owned by root, and I can't get
it back to normal.

Unmounting and mounting manually also does not help:
