It seems the answer to this is because that tor.exe is the 32 bit version of Tor from tor-browser-windows-i686-portable-13.0.10.exe
I get the exact checksums as TORU but Windows Defender does not flag it and neither does Norton.
So ignore the quote from that “artificial intellegence”. It’s BS.
And to answer my question above: Yes, there are different versions of tor.exe 13.0.10
