Excuse my inexperience but this project was started with a high-level engineer who was then hired by a giant and dumped me.
Unfortunately, I don’t find people who know how to work with certain new frameworks.
No need to apologize, this forum is here for questions.
A final recommendation would be though to fix the platform version in place so that it says fixed even if a new version is released (which might change the Arduino core and introduce incompatibilities). Doing that increases project compilation robustness. You can do so by writing platform = espressif32@4.4.0 instead of platform = espressif32 in the platformio.ini (see releases and docs)
