i have smartcard reader driver which is kmdf driver. My driver is blocked by win11 from starting somehow and in device manager i get following error
The driver for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)
My previous binaries of the driver was signed with win10 system and microsoft partner center. The driver loads and starts properly in win11. Now my system is migrted to win11 and now if i sigh the driver in win11, and try to install, it does not work and blocked by the windows
Below is my modified INF file which is as per the new driver isolation pilicy

is my INF correct.? what can exactly block the driver in windows 11?
Any help would be useful here, since i am currently blocked by this and have no clue what is blocking the driver from starting.
Here is the log from setupapi.dev.log file
