Btrfs snapshots disappearing from timeshift

[laddupeda]

Hello, I recently reinstalled manjaro with btrfs, so that taking snapshots would be easier because my pc freezes too much and i have to force shutdown it with power button almost once every week. But now every time I am forced to force my pc to turnoff, all the snapshots dissappear from timeshift. They do appear in the grub menu however until timeshift creates another backup and they are gone for good.
Upon exploring the timeshift-btrfs subvolume I found that the snapshots were still there but the info.json file was blank. I don’t know what to do any further. Please guide me to the next steps of fixing it.
Thank you.

Gentle shut down a suddenly hanged PC to minimize a chance of getting a broken filesystem and data loss:

[HowTo] reboot / turn off your frozen computer: REISUB/REISUO

Difficulty: ★★☆☆☆ This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means. So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here! If you’re reading this in response to a question, please click the green link above this text to bring you to the full unabridged text of the tutorial…

[laddupeda]

Thankyou, That’s a new thing i learned.
The REISUO works but REISUB doesn’t work. they show same output but pressing O turn’s off the the computer but B doesn’t reboot it, it does nothing in fact. But turning my computer off is satisfying enough for me. Thank you again.
Please don’t mind me not marking your reply as solution just yet because i want to test this during an actual freeze and avoid closing the thread before that. I use wayland so that shouldn’t take long.

[laddupeda]

Thank you so much. It froze and I did manage to shut it down without destroying my snapshots using REISUO.
Thank you again.
