I don't think that any of those warnings is relevant to your problem.
In the meanwhile, I tried compiling with VS2017 and linking against Qt 5.14.2. I could not observe any defect in the Operator module, and batch files worked as they should.

Are there any non-ASCII characters in the path to the directory you are building BCI2000 from?

No, they're all ASCII characters.

I tried to launch the operator.exe from an older version and three other modules from the newest version separately, and this time it says

2020-07-16T10:17:05 - SignalGenerator: Next module's IP/Port parameters not available.
2020-07-16T10:17:05 - ARSignalProcessing: Next module's IP/Port parameters not available.
2020-07-16T10:17:05 - CursorTask: Next module's IP/Port parameters not available.
2020-07-16T10:17:06 - SignalSource confirmed new parameters ...
2020-07-16T10:17:06 - SignalGenerator: Lost connection to SignalProcessing: Unknown error state.

Is it normal?

Yes, this is normal. The Operator module version needs to match the most recent module's, or must be newer.

Hi,

I uninstalled and re-installed everything. And this time I changed the BCI2000 and Qt into 64bit. Though I don't know why, anyway, everything solved!
Thank you for your guidance!
