S23 Ultra: Theme stuck on my phone

[Mojo402002]

Hello Everyone, I have a issue. I was trying out a theme on my S23 Ultra, and have got my phone stuck on what looks like Ghost mold everything has a white edge around it. I tried to reset my phone several times. Do I have to do a factory reset on my phone to get back to the basic setting?

Did you apply a theme from Galaxy themes?

Pinch on home screen > Themes > Menu > My Stuff > Default

You need to un-select the theme that you chose and that's it
