FAQ

Slow compilation on Windows

Symptom: Each file may take up to 3 seconds to compile, and sometimes the process gets stuck on a file.

Solution:

Open Task Manager with Ctrl + Shift + Esc, check CPU processes, find and close the MSPCManagerService process.
If the above does not work, move the entire TuyaOpen directory to a non-system drive (e.g., D drive), and add the directory to the exclusion list in Windows Security - Virus & threat protection settings.
