I have a similar issue.
Here is what happens : I can connect to the hotspot just fine, but the connected devices don't have access to internet (tested with an android device and a windows device).
I tried all the wifi security options one by one, and there is the same behavior with each of them.
The hotspot worked fine with Ubuntu 21.10.
Hope this helps and sorry for the noise if it's unrelated.
