P: PS v27.4 Remove Tool (GenAI: On) is not working and producing artifacts

Hey, ​@Wrivium, & ​@AJ1969vsx. Welcome to the Photoshop Community. I’ll help you figure this out.

In a recent conversation, we confirmed that 'Run as Administrator'—something as basic as that — helps in a few cases. 

Just head to the Photoshop installation folder (Default - C:\Program Files\Adobe\Adobe Photoshop 2025)

Find Photoshop.exe > right-click > use 'Run as Administrator'.

Let me know how it goes.
