@WYWFlash Yes this does happen. On windows, try removing the clang-format from path and you can see that it deletes the code, you can however undo it.

I've found the reason, QProcess::exitCode() is invalid when the process is not finished, I checked only the QProcess::exitCode() but not whether it has finished, thus made an undefined behavior, and result in this bug.
