New App Is Not Removable From Stack

[antigravity]

When I open the stack with the Menu button, I can't swipe the first app on the stack (most left) upwards, it stucks and is not removable like it was locked. I think the problem occured a while after I locked WhatsApp for the first time.

Phone: Xiaomi Mi5S
ROM: weekly(6.12.22)

Sry, I'm dumb as f**k. If the application is in the foreground, it is obviously, that I can't remove it from stack. Case closed.
