Funscript Player Status: Error : Access to the path 'COMX' denied

some funscript player connect games make this error,

while some other funscript player connect games don’t.

I’m using SR1 twist model, and my appsetting.json looks like this

//OSR
“OSRConfiguration”: {
“COMPort”: “COM4”,
“EnableMultiAxis”: true
},

Does anyone know how to solve this problem?
