PYSTACK Exhausted Error #8594
Description
CircuitPython version
I got a PYSTACK Exhausted Error.
Added to settings.toml **CIRCUITPY_HEAP_START_SIZE =** and adjusted it from 8192 up to 32768 with x2 in each step: Not fixed.
Removed CIRCUITPY_HEAP_START_SIZE.
Added CIRCUITPY_PYSTACK_SIZE = 8192: Fixed.Code/REPL

Adjusting CIRCUITPY_HEAP_START_SIZE in settings.toml, as noted in the initial posting of 9.0.0 Alpha 4, does not fix the error on an RP2040.
Description
The code.py above runs on a bare Raspberry Pi Pico W. No additional parts needed.
Your settings.toml will be needed.
I started with the Code the Pico W HTTP Server and only modified code.py.
I removed the ssd1306 code and disabled the DS18X20 pending later use.
The print('nnn Exception :', ex) code shows the approximate line number of where the exception occured.
Additional information
