Subprocess Connection error

[nuu.05.05 at gmail.com]

   Hello,

    

   I have been 3.8.10 version of python until I ran the code for tkinter and
   I started getting subprocess connection error. After this I haven’t been
   able to open python for use as I get this error upon startup.

    

   Please help resolve the matter soon.

    

   Best regards,

   Nuha
