Is PublishAOT necessary for a working app bundle after signing?

Hi there,

I wanted to port one of my games to mac os and have the problem that the unsigned app-bundle runs without problems but as soon as I sign it it crashes (icon is displayed shortly but no window opens and then the icon disappears).
I´ve tried it with the monogame template which works as long as I build the game with the PublishAOT=true parameter. I´ve build the main game as well but it uses XMLSerialization which doesn´t seem to run with PublishAOT.
That´s why I wanted to ask if somebody was able to sign a bundle for the mac app store without using PublishAOT?

Thank you,
Harry
