Archer T3U can't connect to 5Ghz (previous thread by koga)

I tried every tips you posted (https://community.tp-link.com/en/home/forum/topic/217836) but I still can't connect to 5Ghz.
1. At first I couldn't even see the 5GHz version, I switch from canal 100 (auto) to canal 38 then I could see the 5GHz version appear in the list of Wifi.
2. When switch on, I can only see the 5GHz version (2.4Ghz removed).
3. It doesn't seem to do anything.
4. It only works fine in 2.4GHz and only 1 or 2 sec in 5GHz.
5. My phone (Oneplus 9) works fine on both 2.4GHz and 5GHz.
6. It is set this way by default.
I tested 5Ghz with both drivers (the one from 3. and the one from this website https://www.tp-link.com/fr/support/download/archer-t3u/) and it crashes the same way, few second after a connexion to 5GHz.
Help !
Thanks for your fast answer,
I can't show you any error message, the product crashes (it deconnects from the pc) and tries to reconnect to the same wifi and then crashes again, it is hard to have the right timing to forget the 5GHz wifi before it tries connecting again.
I can confirm it is the right password (I tested on my phone) (My pc can sometimes connect few sec to the 5GHz wifi before crashing)
The wireless security option is by default WPA2 and there is no other option.
Here are my wifi settings :
I bought it on 02/09/2022.
