Can you try

$ cygcheck /usr/bin/python3.9.exe
D:\cygwin64\bin\python3.9.exe
   D:\cygwin64\bin\cygwin1.dll
     C:\WINDOWS\system32\KERNEL32.dll
       C:\WINDOWS\system32\ntdll.dll
       C:\WINDOWS\system32\KERNELBASE.dll
   D:\cygwin64\bin\libpython3.9.dll
     D:\cygwin64\bin\cygintl-8.dll
       D:\cygwin64\bin\cygiconv-2.dll


Of course on my system the 3.9 is working fine as also alternatives

$ python3.9 --version
Python 3.9.9

Without Python 3.9  installed python3 should link by default to the next 
in the line (likely 3.8)


$ alternatives --display python3
python3 - status is auto.
  link currently points to /usr/bin/python3.9
/usr/bin/python3.6 - priority 36
/usr/bin/python3.7 - priority 37
/usr/bin/python3.8 - priority 38
/usr/bin/python3.9 - priority 39
Current `best' version is /usr/bin/python3.9.


Regards
Marco
