Walk and Fly Issue(View is changing to perspective)

[prakhar.kanungo]

Hello All,

I work on AS 2022. 

I was working on a model for very long and suddenly the walk and fly popup started appearing every-time I use Shift+Scroll to orbit my model.  If I cancel it, it appears again next time I orbit my model and if I click on change, it changes my model view to perspective. I want my model to stay in parallel only.  Please see the attached image depicting the popup message.

I have tried many solutions available on the internet but none of them worked. 

Thanks
