64 Bit Android Packaging Problem Using Animate...

Really seem stuck with this error message but every time I package my Android app with the latest version of Animate and Harman’s Air 33.1.1.3.00 Animate keeps throwing up this message the moment it transfers the published APK file to any Android device I have connected:

:The device has encountered an unexpected error. Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed To extract native libraries, res=-113]

The app runs perfectly using Animates ADL tool starting with Harman’s Splash Screen. The app had been around for about four years in its 32 Bit form. I have recently returned to Animate to update it to 64 Bit so I only tested it using the included ADL tool as it has had many updates over the years.  I recently uploaded it to Google Play & Amazon and was very surprised to find out it won't install in over 1000+ Android devices! I am using a Mac running software version 10.15.7, Animate 21 (latest update) and Harman’s Air 33.1.1.3.00.

I have tried to self research this problem for a couple of weeks now but can't find a solution anywhere so hopefully someone on here can help me?
