Help - 45 unhandled exceptions

CliffeActual · 09-07-2024, 07:20 AM

Hi. Unsure what happened here - Win 11 / Calibre 7.17; started the app alongside my mindmapper - Freeplane. When I went to the Calibre window I had 45 unhandled exception errors, all variations on the version below; plus one Error communicating with device error (I also had a samsung tablet on USB). Restarted Calibre without a repeat of the errors.

Any suggestions as to whether I need to worry about anything?

No those are transient errors probably caused by the device cable getting loose at just the wrong moment.
