ellipses stuck on screen :( need urgent help!

It’s my first day using this app and I can’t seem to get my brush tool to work normally. When I try paint a weird circle shape follows, it’s hard to explain but it won’t let me get rid of it. i tried opening and closing the app but it doesnt go away either. does anyone know how to get rid of it??/?

You put an assistant on the screen. See Assistant Tool — Krita Manual 4.4.0 documentation for more information about the assistant tool.

its still not working for me… i tried everything

toggle visibility of assistants:
view > uncheck “Show Painting Assistants”

Delete the assistant:
Assitant Tool > Hover over the unwanted Assistant > press the cross sign on the right most side of it’s mini panel.
