Hi all. Subj.
/usr/bin/telegram-desktop: symbol lookup error: /usr/bin/telegram-desktop: undefined symbol: _ZTI20QGenericUnixServices, version Qt_6_PRIVATE_API
5.13.1-2 fixes it, try pacman -Syu.
Could do that only by temporarily disabling artix's galaxy repo and installing from arch's extra repo.
# p -Ss telegram-desktop
galaxy/telegram-desktop 5.13.1-1 [installed: 5.13.1-2]
Official Telegram Desktop client
extra/telegram-desktop 5.13.1-2 [installed]
Official Telegram Desktop client
I tested just now on a fully updated system and there the reported problem does not reproduce; telegram-desktop just starts up fine.

Upgraded system right now (including auto-downgrading telegram to 5.13.1-1) --> error is still there.
What is your output of: ls -l /usr/bin/telegram-desktop

I bet your mirrors are still stale after pacman -Syu. Put those two at the top of /etc/pacman.d/mirrorlist:
Server = https://mirror3.artixlinux.org/repos/$repo/os/$arch
Server = https://mirror2.artixlinux.org/$repo/os/$arch
Then try pacman -Syu again.
I did as you say and it worked. But then I removed these 2 lines, did `p -Syuu` and it didn't downgrade telegram. Also I noticed these two lines in the middle of the mirror list, too. Pity I didn't retry without editing mirrorlist. So now it's good, just in case:
# p -Qo mirrorlist
/etc/pacman.d/mirrorlist is owned by artix-mirrorlist 20250326-1
# p -Ss telegram-desktop
galaxy/telegram-desktop 5.13.1-2 [installed]
Official Telegram Desktop client
extra/telegram-desktop 5.13.1-2 [installed]
Official Telegram Desktop client
After it worked, I re-installed telegram 5.13.1-2 from galaxy repo (re-downloaded because of signature mismatch), works again.
# ls -l /usr/bin/telegram-desktop
-rwxr-xr-x 1 root root 112530928 2025-04-02 22:44:16 /usr/bin/telegram-desktop
I believe it's all good now, marking as solved. Thank you both.
