Current TLDR
Logs below reveal that a job for grub-mount and/or os-prober runs when Calamares is started and hangs on either of my quadruple boot Linux partitions. It seems that os-prober and/or grub-mount tried perhaps to mount my ext4 Linux partitions as ext2. This is prevalent in newer versions of Calamares in two distros I tried, Garuda and Archcrsft, and absent in an older version of EndeavourOS.
TLDR End
Update: Tried Archcraft iso with calamares 3.3.9 and was able to reproduce the exact issue, will now try a different “good” usb. Lol,same results.

From the post:Garuda Install - Calamares hangs on Partition Module
Reveals that grub-mount and/or os-prober runs on my Fedora 41 partition which is /dev/sda16 and idk why it hangs, Fedora has SELinux, any clue that it may cause this ?
Will try taking a snapshot from restic, deleting the partition and seeing if it makes any improvements. No improvements made. It gets hung on another one of my Linux drives/partitions now.
Does it seem to mount my ext4 partition as ext2 ? I am unable to understand anything,lol. Will study os-prober and grub-mount.
