Hi thanks tony, the reason why I think it is the startallback is that the first time I uninstall it, the "choose another app" function is back to normal right after the uninstallation, however, after my pc restart the function is not working again.

3.6.3 want to change the default app to play video/picture but when right click video - open with - choose another app- (no response) unable to set default app to open in under setting - apps - default apps, either. please help even if I uninstall the 3.6.3 it is still not working, same issue on both my win11 office PC and personal laptop.
