I can confirm that the latest update resolves the issue for me.

Regardless, I was having a problem, but now I'm not and that was the only change.

I was able to resolve my background scanning by adding the following permission to AndroidManifest.xml and repacking the APK. I did manually set the "Allow all the time" location setting in the app settings. <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

I had the time to take a logcat while experiencing the issues. I have of course set the battery settings to not optimize and have given the app whatever permissions it has asked for. There are definitely issues with NL80211_CMD_TRIGGER_SCAN, android.hardware.wifi@1.0-service, and NetlinkEvent ...

Just updated my OnePlus 6 running LineageOS 18.1 and am having this issue. Seems that this behavior is related to the September Android security update.
