And it gets stuck at that "removing" loop as far as my patience managed to let it loop.

Also, when I open Timeshift it is empty. I actually have Timeshift on the "start with the DE" list and always do one manual snapshot a day, I did it today, but now after a reboot, there's nothing left there. I panicked and made a snap before opening the terminal and noticing the Json-CRITICAL.

Please be kind on the answers because I'm very far from a linux expert : 3

sudo reflector -a6 -f5 --save /etc/pacman.d/mirrorlist
sudo pacman -Syyu

This will also force a download of package lists and perform the update.
It might help, but I'm afraid the post you found was a different case...
Your problem could be in

Failed to delete directory: /run/timeshift/backup/timeshift-btrfs/snapshots/2021-04-10_21-00-01

As a temporary workaround I've recently learned that you can skip the timeshift-autosnap with
sudo SKIP_AUTOSNAP=1 pacman -Syu

I found this one wihch cold be interesting for you to read and try to solve the timeshift problem:

In my system I also see my snapshots in:
/run/timeshift/backup/timeshift-btrfs/snapshots

I don't have your problem.
But sometime, Timeshift creates snapshots with nested snapshots and Timeshift is not able to delete them. You should delete them with "btrfs subvolume" commands. (First nested snapshots and after the main one)

To investigate, I suggest to use this command.
btrfs subvolume list /

The output should be something like:

ID 257 gen 127297 top level 5 path @home
ID 258 gen 127108 top level 5 path @root
ID 259 gen 43 top level 5 path @srv
ID 260 gen 127297 top level 5 path @cache
ID 261 gen 127297 top level 5 path @log
ID 262 gen 127143 top level 5 path @tmp
ID 471 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-18_19-04-49/@
ID 489 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-18_10-16-27/@
ID 495 gen 127297 top level 5 path @
ID 497 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-19_08-29-54/@
ID 498 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-19_10-11-55/@
ID 502 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-19_18-38-03/@
ID 503 gen 127216 top level 5 path timeshift-btrfs/snapshots/2021-05-19_21-30-32/@
ID 506 gen 127293 top level 5 path timeshift-btrfs/snapshots/2021-05-20_09-38-05/@

In this case, I don't have nested snapshots.

Yay! First of all, thanks @filo and @LorenzoHex for helping me out, I was able to solve the problem!
For future reference on our own forum, the post that @filo found in the other forum solves the problem: I just had to make a new snapshot at the Timeshift GUI and go to /run/timeshift/backup/timeshift-btrfs/snapshots (as sudo ofc) and go to the last folder, copy the "info.json" file and make it replace all the other .json on all the other folders. System is working like a charm again!

Thank you both so much : 3

I also noticed from the post at the other forum that sometimes when the system have any kind of freeze (for me it was with an online game) the .json can get easily corrupted, and it is a Timeshift problem rather than anything else.
So let's keep an eye on that if any other freezes ever happen xD and also an eye out for online gaming on suspicious sites : C xD

Just FYI when you do a manual timeshift snapshot it is not automatically added to your Grub timeshift snapshots choices. You need to do a sudo update-grub after creating the snapshot manually to have it added to your boot menu choices.

I'm glad @filo found the answer for you. Was it a crash that precipitated this corruption in your case?

Hey tbg, thanks for the advice, I'll keep that in mind!

And yes, it was, I suppose the game had some sort of bug that affected the browser that froze the system.
But from what I could grasp from the other forum, the cause of the freeze don't seem to be related to the corruption of the .json files, any freeze can cause the symptom.

Nice to know it. Thanks you.

If you forget to do that you can always update grub from run level 3 at startup if you need your last snapshot to boot.
