After the internal Wifi of my Thinkpad X200 T was not working anymore, I bought a TP-Link TL-WN722N from

Technoethical. I installed a newer kernel for Trisquel 8:
Linux version 4.15.0-112-generic (name at domain) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.12)) #113~16.04.1+8.0trisquel3 SMP Thu Jul 23 11:04:14 UTC 2020
after reading here

and also installed open-ahth9k-htc-firmware after reading here
https://trisquel.info/en/issues/27129
Any Idea what I could do/check to solve the problem?
First, be sure that it is an ath9k-htc. The only problem with ath9k-htc is that it doesn't support MAC randomization, so I always need to create a hotspot first and then disable it before I could connect to any hotspot.
Also, internal (PCI/e) WLAN cards are always first choice, because ath5k/9k doesn't require any firmware. Even if your X200t still runs original firmware, there is still an Atheros card usable. It's an (albeit low-end) AR2425 card with Lenovo's FRU number 43Y6511.
It should work. If I were you, I would use https://tehnoetic.com/index.php?route=information/contact to get assistance (and maybe another dongle).
