Any ideas?

The network is configured with two separate WiFi (2.4 and 5).
We managed to localize the problem.
If you disable the 2.4 network, the problem goes away. If you turn it on, it appears again.

Hello, Andriy, 

As per the information in the log, we see the issue happens only in wlan0 which is a 2.4 GHz WLAN. Also, the disconnection reason stands for code 2 which means 'Previous authentication no longer valid'. It would be important to test different 2.4 SSIDs or even delete and recreate the WLAN. Also, if only one AP is affected with this issue, we could FR to the AP. I read there are a few clients affected, are all the same device type?
With those answers we can narrow down the root cause of the issue.
