Got the latest version (20220416) installed successfully as a clean install in three tries. Here are some notes about what I had to do to make it work.

On my first failed attempt, I installed LineageOS and the suggested version of NikGapps (arm64-10-20220419) without rebooting between flashing the two images. On bootup, althought it got past the flash screen, the setup app kept crashing before I could even choose a WiFi network.

• It's possible that this might have worked if I did a reboot between installing LineageOS and NikGApps.

On my second failed attempt, I installed LineageOS and FlameGApps-12.1-basic-arm64-20220412 without rebooting between flashing the two images. On first bootup, the setup app appeared to be working. I logged in to google during setup and tried to restore a backup from my previous image from google drive, and then the setup app kept crashing again.

• As before, it's possible that this might have worked if I did a reboot between installing LineageOS and FlameGApps.

On my third attempt, which was successful, I installed LineageOS and FlameGApps-12.1-basic-arm64-20220412 without rebooting between flashing the two images (same as second attempt). However, this time I didn't log on to google at all during initial setup (although I did connect to my wifi network). I also didn't set a screen lock during initial setup. The initial setup completed successfully, and I was able to connect to my google account after setup without a problem.

I'm thinking that most likely, my second attempt failed because I connected to google and tried to restore a backup from google drive during initial setup. I'm not sure whether it would have been OK to connect to google WITHOUT restoring a backup from google drive.
