Hi,
I ran the PC Health Check on my HP Envy x360 with AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx 2.00 GHz
It says the processor isn't supported, but it also says PC supports secure boot, TPM 2.0 is enabled, etc. all green check marks. So it is not TPM or secure boot that is the problem.
Must be something else.
