Why doesn't platform idea terminal work in Atom?

Question

atom

Hello, please help me solve the problem in the atom with the platform idea terminal plugin.
When I run the code in this idea, I get the following error:

The name "t.py" is not recognized as the name of a cmdlet, function, script file, or executable program. Check the spelling of the name and the presence and correctness of the path, then try again.
string:1 character:5
+ t.py <<<<
+ CategoryInfo : ObjectNotFound: (t.py:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

Can't fix it, what could it be?
Before that, it worked fine without any problems, reinstalled and it started not clear what.
Thank you very much in advance!
