Fiori leave request error "Could not start the app due to an internal error"

Hi,

I'm getting this error "Could not start the app due to an internal error" when accessing leave request application.

I don't get this error when I login and launch the app for the first time. when I go back to the home screen and select "My Leave Requests" app again, I get this error.

If I close the error message and do a browser refresh, everything is fine again for the first time, if I access the LR app again- same error .

Other apps are working fine.

I don't see any error in gateway or App logs.

below is the Request URI
