You know Aileen...
i was reading a couple of threads with similar error code problems and one of them actually got very upset because you people offered things he already did and mentioned on the original post.
Right now, you just did the same thing which lets me to believe you guys pay no attention to the problem thats been posted upon.
I FIX the issue and it was not thanks to anything Windows 10 could do about it. Luckily my laptop is a Macbook Pro which also has Windows 10 on Bootcamp.
Booted up on MacOS and connected the HDD and i performed a Repair First Aid which is similar to the Disk Clean up i did on Windows 10.
The First Aid repair tool manage to fix whatever clean up was needed to be done.
After that i went back to Windows 10 and was able to set the HDD as the main drive to download Apps and was able to move Forza from my local SDD.
The solution is to use MacOS to perform a Repair Aid(Disk Clean Up) if Windows 10 just doesn’t seem to fix his own mess.
Maybe next time you guys can pay more attention to the main post before suggesting us to repeat processes while wasting more time doing things we already told you dont work.
