Getting console error "fetch is not defined" and the page wont redirect

[nishant-shah-social]

While doing cypress execution, after entering username and password, when I click on the login button, it gives this error on console := "fetch is not defined..." and i wont be redirected to the next page...
However, when I perform the same steps manually on the same browser version, I dont get this error in console and things work fine...
Any idea?
While browsing I came across this issue :- #687, which has mentions of how to intercept and stub Fetch requests...
But, my requirement here is not to intercept any request or stub it, its a normal flow which is not working for me...
i am using cypress 8.4 and chrome 94
Any help will be appreciated
