There was a lot of discussion around the wifi bug in the release discussion.
OpenWrt 23.05.4 - Service Release
It's a lot to read through, but as brada4 mentioned, it is fixed in the 23.05-SNAPSHOT build. So you can stay on the .3 version until .5 is released, or use 23.05-SNAPSHOT (not to be confused with SNAPSHOT which will be the next 24 release). Personally, i opted to move to 23.05 snapshot because i was lazy and didn't want to downgrade and restore settings. I used auc to do that.
