No such file or directory for included library

The project is a library; I contribute to the library and maintain a personal main.cpp file outside of git to test the library.

I highly recommend to change the project structure and pull out the project from the library.
See here for a proper file and project / library structure for local library development.

Why would the file path’s length be an issue?

Windows command lines are limited to 64Kb.
When the filepath is too long you may hit this limit during compiling the project. Run a verbose build (-v) and see how long the command lines are.

Platformio doesn’t even run in WSL for me after installation.

I made a video about how to install WSL and setup PlatformIO. The video was not meant to be public so there is no explanation or voice over. But maybe you can use it to setup PIO in a WSL. (If you ever used PIO in WSL you won’t go back to pure windows.. it’s incredible fast!)
