AAM Updates Notifier Application keeps crashing

I installed PSE 2018 just after it became available. For some time now 'AAM Updates Notifier.exe' crashes on a regular basis, usually at 2am. It has crashed 9 times in the last 20 days, on one day it crashed twice in the space of a couple of minutes. It is version 9.0.0.281.

Is there anything I can do to stop it crashing? If not then can it be uninstalled, and if so then how? It does not show in Microsoft's Control Panel.

Adobe Application Manager, 'PDApp.exe', has also crashed 3 times in the last 20 days, usually about 6pm. Is this related to the other problem?

Any suggestions on how to avoid these irritations would be welcome.

I have gone into preferences and unchecked all of the boxes to see if this makes any difference.
