PC refuses to sleep when OS installed on USB SSD

[Karola]

My pc used to "go to sleep" without any issue.
latly ive install my windows on protable ssd drive, and since then "Sleep" is shutting down pc.
the option "sleep" is visible but it's actually shutting down the pc.

BTW: when i restart my pc through the internal drive (m.2 drive which is on motherboard) sleep mode is possible.
both win versions are 20H2

Is there anyway to put pc on sleep mode while windows is running on usb ssd?

i followed these instructions but it did nothing:

I'm very sorry, sleep and hibernatemode in the latest version of Windows 10 seems to be available on some computers and not available on some computers, there is no way to solve this problem for the time being. Please accept our apologies for any inconvenience this may have caused.

I followed the instructions with other windows version and its goes perfectly, thank you!!!
