Hi @hoangnm

Thanks for the logs, they helped a lot. I managed to reproduce a very similar failure on my side: a project living inside WSL, opened in PhpStorm on Windows.

I can’t say for sure what triggers it in your case yet, but my working theory is that it’s related to how the files are accessed over the \wsl.localhost... share, Windows can’t always turn those paths into valid file paths (for example if a file has a name that’s fine on Linux but not on Windows). When that happens, listing the project files fails, so the analysis never starts and you just get the generic “Internal error”.

Either way, a possibly reliable workaround (if the above theory is correct) for now is to not go through the network share at all: open the project using JetBrains’ WSL / remote development backend, so PhpStorm (and our plugin) run inside Ubuntu itself. The paths stay native Linux that way and the problem should go away.

We’ll keep digging on our end to handle this more gracefully. Looking forward to hearing from you whether that worked!

Cheers,
Vasilis
