Siril integration with Starnet++ dose not work

I am a new user of Siril. I have installed Siril 1.4.0 beta1 and Starnet++ v2 command line. I have set the preferences to use starnet++, but it dose not work. I get the following error messages. Can you help?

Running command: StarNet
10:38:01: Spawning StarNet failed during version check: Failed to read from child pipe (EOF)
10:38:01: Error: StarNet executable (C:\Users\manoo\OneDrive\Desktop\StarNetv2CLI_Win\starnet++.exe) is not valid.
10:38:01: Error in line 18 (‘starnet’): generic error.
10:38:01: Exiting batch processing.
10:38:01: Setting CWD (Current Working Directory) to ‘\Users\manoo\OneDrive\Desktop_Session\C65’
10:38:01: Script execution failed.

I have done my initial investigation:

  1. tested StarNet++ offline, separate from Siril, and it works fine
  2. I have checked for both AVX and AVX2, there are both are present
  3. OneDrive is not used, but Siril house setting points to C65 correctly
  4. No Starnet problem when using Siril 1.20.0
