Read link completely first (then decide if you want to disable):
sudo btrfs quota disable /
This will impact timeshift, but possibly might help with your issue.
Btrfs documentation regarding adding quota support in BTRFS:
https://btrfs.wiki.kernel.org/index.php/Quota_support
I believe this is enabled by default on most Garuda editions (definitely with KDE).
