Adding a random background in WhatsApp on my A54 not a good ideaA54

Added a random image as background in Whatsapp. This was not a good move. 

My A54 5G phone will not let me remove it. Furthermore, image pops up as background in Google Chat aswell.

I uninstall both apps, but image returns.

Any idea how to forever remove background?
