BitDefender quarantine on pyinstaller PKG - false positive ?

Hello,

We have a small program that used to be compiled with pyinstaller (python executable) and recently it happened that pkg parts of the compiled file are quarantined with the following message:

L'analyse à l'accès a détecté une menace. Le fichier a été supprimé. C:\<path to file>\RCX555B.tmp est un malware de type Generic.Dacic.A05F649C.A.D1528439

(Sorry it's in French), basically it says: "Access analysis has detected a threat, The file has been deleted c:\<path to file>\RCX55B.tmp ..."

Could that be a false positive and how can I avoid that failure ?

We are using pyinstaller 3.11.1, the command is:

pyinstaller --specpath ../../obj/<SolutionName>/spec --distpath ../../bin/<SolutionName> --workpath ../../obj/<SolutionName>/build --onefile <SolutionName>.py 

Command output is a collection of permission denied (after being quarantined) on PKG files:
