First, please do not restart OctoPrint by pulling the power plug from the Pi. Sooner or later you will have a corrupted file system on the SD card.
The first serial log ends before the hotend reached the desired temperature. You may not shorten it.
The second serial.log is not enabled.
In the second octoprint.log:
Before anything important could happen, someone pulled the plug.
Like this: OctoPrint was about to start to print - and woosh - hard restart.

There's a lot of resend requests in the octoprint.log, hinting at general communication issues. Try a new USB cable, shielded and preferably with ferrite beads. And make sure it is not near any high power devices such as the motors, or appliances such as fridges or microwaves etc. since they can cause interference.
Having the same issue since this morning (the update to 1.5).
Printer: Crealty CR-6 SE
The printer has been running since early Nov without any issues (working perfectly). After the update, now my printer is not working (prints are not starting - no temp, no movement). I can send files to the printer, move it manually, change temps.
When you press "PRINT" it just does nothing.... Help
I have tried rebuilding the Raspberry pie from the ground up... still having issues.
Tried Safe Mode - this is working.
Looks like Octolaps is the issue *Disabled, and seems to work.
