”PixelLauncher Crashed” After fully clean flash of customer rom

This ”PixelLauncher Crashed’ seems to happen more often. Might come from the LineageOS origin, as all custom ROM’s are based on that.

I had to fully clean flash my X3 Pro due to issues with Magisk. But now I continuously run into this PixelLauncher Crash. No matter if I try NikGapps-CrDroid or NikGapps Omni or Mindthegapps.
Clean install, wipe dalvik/cache/data. Adb sideload without errors.
But upon first boot at the first initialisation screen, a popup of pixellauncher crash.
What is this? I’ve seen people post at LineageOS forum too. But could not find a solution Found tenorshare.com/fix-android/fix-pixel-launcher-keeps-stopping.html but didnot help me.
Just now I clean flashed the ROM without any Gapps, and surprisingly the launcher is working.

Update: in Recovery I flashed this Nikgapps, wipe dalvik+cache and it still runs okay.
Conclusion; better boot on the ROM first before continue applying Gapps.
