Various Illustrator issues since latest update (28.1) on macOS

I have several bugs that makes working with the software almost impossible. I have Illustrator 28.1 running on Sonoma 14.2.1

Issues I've found already are:

• Can't align items to artboard and to each other
• Rulers set to artboard rulers, but when I'm checking an item in the Transform panel it sometimes shows really odd numbers (like -2856 mm)
• flickering ghost images from time to time
• After duplicating an artboard the items on it aren't aligned the same way anymore (like if I'm using a filled rectangle as a background it moves away from the sides of the artboard)
• I've selected items on the same layer on an artboard and with it Illustrator selected other items on a different artboard that wasn't even on the same layer
