Can't Login into macOS after Linux install

I have a MacBook 7,2 with macOS Sequioa, also with a dual boot with windows which both have worked fine.

I then splitted my main partition to have a partition for Linux Mint which I then installed successfully. Before I configured my EFI before insatlling Linux Mint so that it shows up in the Open Core Boot Menu.

Now when I boot up and choose macOS, it shows me the macOS Login-Screen, but after entering my password nothing happens and there is just an empty screen with my profile photo and the wallpaper. I reckon I somehow got locked out of my macOS filesystem?

I am pretty clueless what to do, since it's a quite special combination of aspects my Laptop has so I hope you guys have an idea. I can access the EFI partition from my Linux Mint so I reckon I have to change some settings from there?

I'll be totally glad for any tips!!
