Welcome to the forum @D100
To temporarily dismiss such popups, use the Dismiss button:
however the current goal for the Experimental channel (which you chose) is to test updates.
This happens after Canary channel looks good enough, but Experimental is rare, as is Beta.
Typically, Canary becomes Experimental becomes Beta (widely used) unless issues occur.
So thank you for being the first report that I can find of exactly this issue, and let’s look at it…

A search for “KERNELBASE.dll” “6.1.7601.23796” is getting mostly pages from 2017. What OS is this?
System.AppDomain.ExecuteAssemblyByName
is noteworthy because it means you either have a very old Duplicati base version, or are asking for this outdated update method which is giving some other people some trouble (and the exact trouble varies).
Duplicati.GUI.TrayIcon.exe 2.0.1.73
suggests that your original Duplicati installation from .msi was using 2.0.1.73_experimental_2017-07-15
Unable to start up after upgrade from 2.0.5.108 - to 2.0.5.110 - System.ArgumentException: Illegal characters in path. #4295 gives history and troubleshooting techniques which found trouble with very old base version of Duplicati starting very new version of Duplicati. Solution was to reinstall base from .msi.
Although you can find your base version anytime by reading C:\Program Files\Duplicati 2\changelog.txt, Downgrading / reverting to a lower version shows where previous updates might be. You may avoid the startup crash on 2.0.6.0 by going back to whatever you had before. Was it 2.0.5.0 Experimental before?
