You are running:

*** [ DIAGNOSING ]: FTL version
[✓] Version: v5.19.1

So your observation seems like another instance of FTL crashed [Fixed in 5.19.2] · Issue #1478 · pi-hole/FTL · GitHub, for which a fix is available in v5.19.2.

Run pihole -up to get that fix.

Updated! Thanks!

like in the bug your link, i updated it recently, after working with Pi-Hole for 2 full years without crash
