I've had a quick read of it and you should start looking from the following timestamp:
[2020-04-25T02:28:56.092 AUS Eastern Standard Time INFO ][ org.kde.kstars.ekos.capture] - "Telescope completed the meridian flip."
From this point the alignment module kicks in and tries to solve. It attempts to re-align for the rest of the night with no luck. The last "Solver Failed" mesage I can find is at timestamp:
[2020-04-25T02:41:41.729 AUS Eastern Standard Time INFO ][ org.kde.kstars.indi] - Astrometry : "[INFO] Solver failed. "
Then the mount/Ekos sits in a never ending loop of aligning until I killed it at 5:00am this morning.
