Illustrator bugging in diverse ways

Hey, 

I've used illustrator for many years and would say that i am familiar with the program. 

For the last two weeks, however, it has acted in strange ways. Problems occur - I reinstall the program - it works for a couple of hours before coming back again. I say "strange ways" because the bug is not consistent to a single issue - they vary. Let me list the bugs that I experience: 

- When applying dash to a line through the stroke function, a thin line is drawn between the individual dashed (center). If i try to apply a gap between each dash it automatically becomes solid. Functioned normally after reinstalling the program. 

- When plotting a PNG all layers is plotted, including those that are hidden. It appeared to follow a specific file and does not occur with other files ive created since. 

- Using eyedrop tool on a pattern does not copy it, but rather the colour of the pattern (fixed through restarting the program). 

- Using rotate-function solely on patterns do not function /does not show in preview (fixed through restarting the program). 

- Dragging a selected object to another layer using the small rectangle next to the layer it is in does not function /makes illustrator black out for a minute before continuing to function. 

Does any of this make sense? Does anyone / Adobe have an answer as to why this is happening / how it might be fixed? Other than the bugs listed above the program seems to be functioning correctly. I am using Illustrator 27.6.5 right now, but have tried installing versions down to 26.5 to see if it might help (which it did not). 

Sincerely, 

Bendik
