"This PC can't be upgraded to this version of windows."

Hello, I am trying to install Windows 11 on my PC as today I was informed Windows 10 would soon stop receiving support. I went through everything to enable TPM on my PC and went through PC Health Check, which told me my computer was fully compatible with Windows 11 and that I can install it, so I begin the installation using Windows 11 Installation Assistant, and after about 2 hours, it finally gets done and I'm met with-

"This PC can't be upgraded to this version of Windows. Your PC isn't supported yet on this version of Windows. Windows Update will automatically offer you this version of Windows once resolved."

So I go back to PC Health Check, make sure I wasn't seeing things, and then ran the check again. Still, it says that my PC meets Windows 11 requirements. I'm very confused as I don't know how my PC would be unsupported? My specs are:

GeForce GTX 1050ti

Intel Core i3-10100

Gigabyte B460m DS3H motherboard, BIOS updated to 2020, and the mode is in UEFI.

I have a hard drive with 30gb free, and an SSD with 230 (Windows 11 Install Assistant was downloaded to the hard drive, which doesn't have that much space available, so maybe that's it? But the website says I only need eight gigabytes free, so I'm not sure.)

And as I said earlier, I enabled TPM in my BIOS so everything should be good to go, I'm really confused so any help is appreciated.
