Can’t use Life Flask – health doesn’t recover (No error message)

I’m having an issue in Path of Exile 2 where I can no longer use my Life Flask. It worked fine when I first started playing, but suddenly it stopped healing my character even though the flask is equipped and fully charged.
• The hotkey is working, but it has no effect.
• No error message shows up.
• I tested different flasks and keys.
• No curses or debuffs are shown that would prevent healing.
• I verified my game files and tried reinstalling.
• The issue has been ongoing for several days.

Is this a known bug or is there a fix? I’d appreciate any help or clarification from the dev team or anyone who’s experienced the same issue.

Thanks!

Are you playing a Lich with Eternal Life ascendancy?
