Extremely large log file

Ended up with 9GB+ logfile last night where 99%+ is this message:
[09/18/21 04:31:43.451][ERROR][Telescope Thread][SQ;AF;] Exception in telescope dispatch! : Thread was being aborted.
at System.Threading.Thread.SleepInternal(Int32 millisecondsTimeout)
at s2.afa()

I believe what has happened is that SGP has gone into safe mode, then woke up and found no target available (nothing was setup after 4:10 i believe) and just didn’t know what to do.
This is the message that appeared on screen reported by my friend.

Here’s the archived logfile, it has to be opened with ultraedit because notepad and notepad++ won’t open it.
