Hello, I don't know if this would help, but I am having similar problems as mentioned before. NetworkManager stays stuck on "Setting Network Address" for some time, and then fails with "IP configuration was unavailable".
Rarely, it does successfully connect and works fine for a few minutes, but eventually the connection breaks down and no packets go through anymore.
Here are my logs for unsuccessful connection attempts: https://pastebin.com/CdebGueB
I filtered irrelevant entries but kept those that belonged to NetworkManager or kernel messages that seemed to be related to Wifi in some way.
I'm using NetworkManager on KDE with kernel 5.7

If you encountered any problems, set debug log use
echo 5 > /proc/net/rtl88x2bu/log_level
ormodprobe 88x2bu rtw_drv_log_level=5
, and post your dmesg and network managers logs to https://pastebin.com/ .
