After updating from MacOS Mojave to MacOS Monterey, standard apps being freshly downloaded via webbrowser as .dmg file (not via App Store) don't start anymore, e. g. Firefox: https://www.mozilla.org/de/firefox/mac/ DBeaver: https://dbeaver.io/download/ Open Office: https://www.openoffice.de/openoffice_download_macosx.php ... The effect (always reproducable) is the following: A new dock icon pops up dock bar, keeps bouncing for about two minutes, then it stops bouncing, but neither the app starts nor an error message is shown. In parallel, a warning "CoreServicesUIAgent Connection from process XXXX does not have the required entitlement com.apple.private.iscsuia" is logged in the system log (this is always reproducable). What can be the reason that none of the apps are starting? What could I do to make them working again?

Via jpackage from java jdk (17.0.2) we generated a .dmg on a Mac Monterey (12.3.1), including codesigning (using fresh Apple Development Id certificate). Then we notarized and stapled it and uploaded the resulting .dmg to our webserver. The problem: if downloaded the .dmg in the terminal app via curl -O https://xxxxx/my.dmg, click the downloaded .dmg and the application icon in the window that opens, the app starts as expected. if downloaded the .dmg via the same URL in a web browser (e. g. Safari or Chrome), click the downloaded .dmg and the application icon in the windows that opens, the dock icon keeps bumping and the app doesn't show up, without any error messages. For both downloads, spctl shows source=Notarized Developer ID, and no issues were reported in the notarytool log. Further, both downloads are binary equal. How comes that the "normal" download does not launch?
