@dalto just fired up my laptop and tried it on there.
it looks like if i try to delete @ then it asks for are you sure ? yes then it takes you too asking for root password, not you cannot delete mounted volume.
Also you cannot load btrfs subvolumes until you load btrfs data in general first
hope this helps

Can I see a couple of more things from that machine?
findmnt / -o source,target,uuid
sudo btrfs fi show
That is because it doesnβt know which device to read the subvolumes from if you have selected a device yet.

Does yours not have the first line with the UUID?
Also, what is the deal with the ~~~, is that your terminal truncating the output or something else?
EDIT: nvm, I see your output is just misformatted.

It looks like the output from findmnt --real is truncated, the options are cut off in the middle.
Realistically, it would probably be better to load the btrfs data when the application loads. The only reason I didn't is because it would cause a password prompt.

May i help in something?
Love the diagnostic thing. Maybe save the data in garuda's private bin?
The btrfs information, in the device selecter instead of the uuid can the device name be used?
It asked me for confirmation to delete my home volume, Now i don't feel like pressing yes. So is their a failsafe after this stage or before this stage?
Those outputs are small so I think it is better to encourage them to post them directly in the forum than on privatebin. The copy for forum button adds the formatting tags for the forum.
That was my original intention but btrfs volumes can span devices so the only reliable indicator is UUID.
Right now, you will get asked for your password if it is really going to proceed. Donβt enter it if you donβt want your data to be deleted.
That being said, @TilliDie pointed out the same thing. Right now, the confirmation question is the first check. It should probably be the last check.

I am going to look at the way we are handling data there and see if there is a way we can preload data without asking for a password multiple times.
I also need to change the defaults for those bars to 0 instead of 24.

I also show nothing in btrfs general tab, and when I go to Devices, nothing shows up there. Also the subvolumes tab is empty.

The solution is probably also the same. You need to hit the load btrfs data button.
