I am new and I just installed Unity to my computer. However it cant start after I registered and logged in.
It just kept going on and on like this:

Can anyone solve this problem for me?

Did you try turning it on and off again?

It looks like it’s trying to connect to your online account and the cloud but is not able to and hence retrying ovwe and over again. Possibly internet problems.

Try also updating your computer hardware drivers like the graphics card, etc.

You could also try reinstalling. If that doesn’t work then try installing an older version and see of that works.
