My Canary install lost the taskbar, settings and few other parts to Windows so I have gone back to an earlier time.
I think what caused the problem was the code trying to get Snipping tool work and should have taken notice of Fg2001 post about, but no I had to try myself.
Yes, that is making the system unusable. I had to restore the backup. 😝😵💫
The default app setting is not working either, so there is no current fix for the problem. 😝🤷♂️
