Creative Cloud constantly prompting me to sign in

Hello everyone, there's something wrong with my Creative Cloud. I am constantly being prompted "You've been signed out. Please sign in again to continue using Adobe apps." screen. I have used Creative cloud before, but that was a year ago. The licence at that time was also from my school, but this year our teacher didn't sign up for it because it wasn't necessary. Now, I created my own account, and I subscribed to Creative Cloud to continue using these services, but then this happened.

I tried finding solutions to it, like in previous articles. I've tried some methods:

They both didn't work. I also did an AVG scan, there were no viruses. I even uninstalled all anti-viruses on the computer. It is still not working. I signed out of the school Microsoft account, so only my account is on the computer. It is STILL not working. (My OS is Windows 10) Can someone help, please?
