Yeah, it messed up my phone and I had to wipe and re-flash everything. Next time I won't try to install an OTA when I wake up and check my phone. And I'll check this thread for reports of problems first. Because I don't enjoy having to setup my phone and apps again.
So updating breaks gestures and removes it from settings so i;m stuck with no navigation and Pixel launcher crashes... but re-flashing GAPPS fixes things. But since I am forced to format my SDcard by the rom when I flash it I didn't have GAAPS on my SDCARD. The Update auto flashes Magisk so maybe it does GAPPS if it's on the SDcard... I'll find out next time.
I haven't formated my sdcard in a long time maybe years, I was really frustrated LineageOS made me format it when I flashed the Rom then I reflashed because I didn't know updating required GAPPS to be flashed again. So both times Lineage OS made me wipe my SDcard...I'm assuming it will do that every time.
So you use GAPPS but don't have to reflash after OTA updates? I use open_gapps-arm64-10.0-stock-20200604 from the the OP. When I update I have to reflash that to get navigation and Pixel launcher working again. The Gesture options are missing from settings until I do.
