show gestures when screenrecording - Apple Community
Whether or not the absence of touch-point gestures being missing from Screen Recordings is an intentional change to iPadOS functionality is intended - or not - is unknown.
You would be best advised to:
a) Seek assistance directly from Apple Support.
You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

b) Submit both a Bug Report and a Feature Request via Apple Product Feedback Portal
For iPad and iPadOS:
Feedback - iPad - Apple
When submitting a Bug Report, ensure that you include your iPad model and the currently installed version of iPadOS within the body of the report. Don’t rely upon the model/version pick-list as this is often several versions behind.
