"...After Installation I Installed My Drivers And Windows Updates. After that I ran a Debloat Script. .."
What is a Debloat script ? Is it an .exefile or a .bat / .cmd script ?
As I understand from its name, it is a small program to remove some default programs, called bloat, off of your PC.
If this program is not for Windows 11 or is not made specifically for it, Debloat script may have made a mess of the file associations of Windows 11.
As Sibro.o suggested, it is better for you to start from scratch at this early stage.
By the way, I am also running Windows 11 on a very incompatible machine currently.
My cpu is incompatible.
My disk partitioning is incompatible.
I have no TPM.
I have no UEFI.
I have no secure Boot.
"...I'm Running Windows 11 on unsupported device. I made an ISO and Installed it...."
By the way, where did you get the ISO ?
Hope this helps.
