Very interesting. Hmm. Iโm not a windows user myself but my first thoughts:
Does this happen with other apps?
This article is about a different error message, but Iโd guess that some of the troubleshooting steps would be the same. Iโm assuming youโve tried those already.
While I am sure this is not the answer youโre looking for, have you tried out Postman in your web browser? This might tide you over in the mean time.
