Freezing of Octoprint when not in safety mode - happens while printing but also when idle
checked the logs, checked if there is any throttling or under voltage or over temperature

I have been working with Octoprint for more than two years now and print almost daily.
Recently I have again the problem that Octoprint freezes regularly. This happens both during printing and when idle. I already had this problem once a few months ago and I could fix it then only by after a complete reinstallation of Octoprint (without importing a backup). Then everything ran without problems for a long time.
After I gave my Ender 3 a firmware update last week, the same problem occurs again. However, I strongly doubt that the update is the trigger.
I have tried several adaptations, to baud rate, buffer size, in firmware and in Octoprint settings etc. and have watched the Serial.log and Octoprint.log. However, I simply cannot assign the cause.
Since everything works fine in security mode, it must obviously be one of the installed plugins. I have already rummaged through the various logs - but could not find anything so far.
What would be the best approach to get to the cause of the error?
In the attached system info bundle, I manually disconnected and reconnected the USB cable at 2022-06-15 07:41:02. At 08:15:47 I then started a print. At 08:28:09 Octoprint froze ... printing stopped. Only a complete restart of the Octoprint service helped.
