@Speciman Can you try the following & check again -
Close Animate
Go to folder - "C:\Users\<username>\AppData\Local\Adobe\Animate 2021\en_US\Configuration\".
Delete the "Coachmark" directory.
Reopen Animate & check Help>Hands-on Tutorial.
There will be only 6 tutorials initially and it takes a while to download other tutorials. Hence, make sure you're connected to the internet. Let me know how it goes.

As of now I have installed version 21.0.1 build 37179.
Yesterday I tried kglad's suggestion which did not work. Today I started Animate to check on the other hands-on tutorials and all of the sudden I am actually able to open them
Either it had to take some time before changes were made or something else has changed up the situation, now I will try those other tutorials which I'm asked to make as homework.
I have attached two screenshots:
#1 represents my starting screen and the tutorials I actually were able to perform
#2 On starting screen, the remaining hands-on tutorials I could not open and on which I received the errors.
As I mentioned earlier, you will be able to start only 6 tutorials in the first launch after installing Animate (i.e. Pig Run, Farmer Walkcycle, Amusement Park, Icon Animation, Animating a doll & windmill).
The rest of the tutorials would take some time to download & load depending on your internet speed.
Now that you're able to start some of those, I am sure you'll be able to launch all of them that are listed in Animate.
You can even consider updating your Animate back to 21.0.6 - you will not face this issue again.
I have done as you instructed and it didn't solve the problem. I was able to open pig run from Help>Hands-on tutorial but not for example Rotating on the Earth. Also reset to default all that was possible in preferences.
