Playing now, game doesnt start BO6

as above, the playing now button just stops and goes back to play. my game wont start. i have uninstalled, deleted and full format. any ideas please? tyia

First some info on my pc:

Intel core ultra 7 265k

Asus z890 f Bios (1501)

Corsair Dominator 32gb 7200mhz

Asus RTX 4070 ti super. (572.60)

Windows 11 24H2 26100.3194

I have tried:

scanned and repaired

Deleted cache and %program data% files

Uninstalled battlenet and game

Reinstalled and redownloaded game

Tried installing on seperate hdd

Formatted windows 11 and tried with just nvidia drivers. (no microsoft account linked)

Installed different version of windows

Downgraded gfx drivers

Factory reset modem

Tried another modem

Run as administrator with compatibility mode win 7

Disabling all firewall

No matter what I do even with a fresh windows it says playing now, then just stops showing the play button.

Is it possible that my hardware has been banned for some reason?

Any other troubleshooting advice is appreciated.

Thank you.

Nathan.
