AppCenter crashes

The issue is described as below.

In order to have working app-center again, you will have to uninstall the flatpak bundles that you might have installed earlier (This is temporary, until we ship a fix in next OS update).

  • Open Terminal
  • flatpak uninstall -y com.rstudio.RStudio
  • flatpak uninstall -y com.microsoft.winfile

Restart system and see if app-center works. Let us know.
Thanks.
