Cleveland Art PyPortal Project Exhausts Pystack #10235
Description
The project from this learn guide: https://learn.adafruit.com/cleveland-museum-of-art-pyportal-frame
Is unable to run on CircuitPython 9.2.7 on either Pyportal or Pyportal Titano. I did not try earlier versions to find the last working one, but could if that is helpful.
Here is its output include stacktrace. The project code wraps the exception with a message about the SDCard but the rest of the trace shows the root cause is pystack exhausted in the network stack libraries.

Feel free to move this issue to where ever it would be most appropriate, I opened in the core because I tried with latest stable release 9.2.7 and many of the networking libraries installed are frozen into the build.
