TX50E wifi 6 driver update - 5G signal not available

I installed a new TX50E wifi 6 pci-e card in my desktop PC. Everything works fine with the wifi 6 driver from the TX50E support page :

I have DriverEasy installed which checks for latest drivers and it installed the latest wifi 6 driver from Intel :

and now 2.4G channel works but 5G channel doesn't.

Had to roll back the driver to fix the 5G. Anyone seen the same problem or have any suggestions?

Thanks.
