Microsoft Store will not allow me to download on windows 11 home

I purchased a desktop pc today brand new from walmart for my kids and I am trying to download roblox for them. I can't seem to get anything to download from the Microsoft store. When I try to download a program ir will say initializing authentication and then say error something went wrong on our end. I was able to download minecraft launcher and purchase the minecraft subscription but when trying to install the game, it goes directly to error and will not download. As far as I can tell my system meets all the requirements and should not have an issue with these programs. I have been all over the internet. I've tried many many different resets and restarts. Nothing is working. Does anyone have a recent trick that has worked?

I have already:

-Signed out and back in to the store

-Changed clock and date settings

-Gone to system>system components>Microsoft store> repair and reset with a computer restart

-Run the wsreset.exe

-Updated all apps and made sure my registration says active.

-Made sure my windows 11 home is updated And not running in S mode

-Ran Windows store apps troubleshooter (says it couldn't identify any problems)

-Used System File Checker, as explained here (which reported no issues)

-tried to download the xbox insider hub (that won't even download)

-Went back through and enabled all privacy settings and permissions

-after every attempted fix I restarted the PC

My poor kids were so excited and after 4 hours of fighting with this thing, I had to put them to bed disappointed. I am hoping there is someone who has recently found a fix. Thanks so much for any help you can offer!
