AppInstaller 1.17.10751.0 - App is no longer starting

Hello,

we have installed an app by installing it via a downloaded appinstaller-file from web. The appinstaller file has the following UpdateSettings inside:

  <UpdateSettings>
    <OnLaunch
      HoursBetweenUpdateChecks="0"
      ShowPrompt="true"
      UpdateBlocksActivation="true" />
  </UpdateSettings>

The uri of the AppInstaller and MainBundle is a website, not on a local file system,

Updates has been delivered without problem right now. After we switched from AppInstaller Version 1.17.10271.0 to 1.17.10751.0 we got following error when starting the app:

(it means: app package cannot be opened. reason: unknown error)

When I check event log (protocol: Microsoft-Windows-TWinUI/Operational) I got following error:

When we roll back the appinstaller to the previous version everything is working without problems.

Do you have any idea on how to solve the problems? Where to set up APPINSTALLER-updatesettings?

Regards
