Hi Krushna,
As far as I know, targeting a newer Android API level is mainly handled in the Native Template rather than Studio Pro itself.

If you're on an older Native Template, you may first need to update it to the latest version before changing the target SDK.
Kindly mark this as the accepted answer if it helps.
Just wanting to let you know I have made a Ticket with Mendix Support on July 28th for this same exact issue, and their response was:
"We checked this with our R&D team and they already have started working on the implementation to support API Level 36.
We will keep you posted as soon as we have more information. For now, I will place your ticket on Hold and update you once the fix is released in coming weeks."
I am assuming they will come out with a new Native Template version, as Krishnakumar mentioned, which we then need to implement and build with.
In the meantime, it's possible to ask Google for an extension period (until november 1st), as you are essentially waiting for a vendor to fix the issue.
