Adafruit Trinkey Proximity issues with version 7.2.1 and beyond not running code for more than a sec

[timid fiber]

I am having trouible with the latest version of the UF2 file for the Trinkey Proximity. Versions 7.2.0 appears to work, but version beyond 7.2.0 seem to only run the code.py for a molment and then report green flashing light every 5 seconds indicating that the code completed. But my code is an infinite loop with a "while True: "

Any help in understanding this would be helpful.
