QT PY S3 (No PSRAM) crashes at write with an initialised display. Metro S3 with PSRAM is fine.

On staging, testing a 128x64 SSD1306 display, that worked previously with the board, but upon reboot has a problem.
Reflashed latest code that works on metro s3 and still same issue.

Don't see anything useful in serial monitor:

I diverted for a bit, but am going to add the ESP32S3 devkit with no PSRAM as a board/build target, as that's the only other one I have with debug port and no psram
