Itunes in new pc: "You do not have enough access priviledges for this operation'

I have a new windows 11 PC and installed iTunes (version 12.12.10.1) - Several problems that I have never encountered with previous PCs:

1. 1. Startup floating message: "You do not have enough access priviledges for this operation"
   2. Authorization - I can't authorize the PC, error message: "This action could not be completed. Try again"
   3. Sign in to account - I can't sign in with my apple ID through iTunes, same message ": "This action could not be completed. Try again"

I uninstalled and re-installed iTunes several times, I tried using a local windows account, linked hotmail windows login and running iTunes as administrator. Same errors. This is frustrating. Wondering if the community as encountered this with windows 11?

(As I can't authorize the new pc and this submission requires an authorized PC, the listed one is my old pc)
