Is it opening the Rockstar launcher in the background?

Press the steam button, see if its opened a seperate window (near where you’d exit the app)

Or try opening in desktop mode and see what happens

UK 1TB - Ordered 630pm on Thursday.

Arrived today at lunch time.

Migrated from LCD to OLED using CloneZilla back up. My LCD has been completely restored to the OLED with no issues. All my decky settings, steam art dB customization, css loader. All moved over without a hitch 🙌🏻
