[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Knobias:
Thanks to support the 6T!!!

edit: I found the issue. I used an old LOS 19.1 boot image to patch magisk and then flashed the LOS 19.1 to my device running LOS 20. Using the correct LOS 20 boot.img in magisk is fine. No isues so far.

I cannot scan for wifi networks and can't connect to known wifi networks. Does anybody has the same issue on LOS 20? I can provide logcat.

LineageOS version: 20

LineageOS Download url: https://download.lineageos.org/fajita

Gapps version: MindTheGapps-13.0.0-arm64-20221025_100653

Did you--

wipe: no

restore with titanium backup: no

reboot after having the issue: yes

Are you using--

a task killer: no

a non-stock kernel: no

other modifications: magisk and MindTheGApps

Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:

It worked on latest LOS19.1

logcat snippet from startup filtering for error messages and wifi. I can provide more on request:
