after I loaded the Adafruit NeoPixel 1.10.7. lib Compiled AOK, and Uploaded AOK.
This is what I got after uploading as-is and pressing reset upon successful reset.

to recover I loaded this and it’s back to working correctly.
/* The true ESP32 chip ID is essentially its MAC address.
This sketch provides an alternate chip ID that matches
the output of the ESP.getChipId() function on ESP8266
(i.e. a 32-bit integer matching the last 3 bytes of
the MAC address. This is less unique than the
MAC address chip ID, but is helpful when you need
an identifier that can be no more than a 32-bit integer
(like for switch...case).
