Hello anybody can help me to solve this issue?
I launch PyInstaller and it systematically stops here:

0.02s - Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off
0.00s - to python to disable frozen modules.
0.01s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.
C:\ProgramData\anaconda3\Lib\site-packages\paramiko\transport.py:219: CryptographyDeprecationWarning: Blowfish has been deprecated and will be removed in a future release
  "class": algorithms.Blowfish,

We need way more context that this. Is this a build or runtime error? What commands are you running? Is this really all of the output? Do you have any idea what this debugger is? Does this happen with a simple print("hello") program or only your specific project? If so, can you track down which lines make it happen and create a minimal sharable reproducible example from there?
