Huge problem: can't remove "bubble" icon from my android

I just installed CCleaner on my Pixel 6a (andoid 13) and it added a weird circle on the side of the screen. I can move it from left to right to left again but if I tap it, nothing happens. I can't find anything on how to remove it. Please help, this is a big problem for me.

I already disabled bubbles globally from the settings (Settings > Notifications > Bubbles, + restart device) but the bubble is still there.

Turn off ccleaner in android accessibility settings. Or at least turn off shortcut in the android settings for ccleaner accessibility.
