Homebrew installed python on mac returns weird response including "line 1: //: is a directory" & "line 7: syntax error near unexpected token `('"

When I run python3 I get the following

 % python3
/opt/homebrew/bin/python3: line 1: //: is a directory
/opt/homebrew/bin/python3: line 3: //: is a directory
/opt/homebrew/bin/python3: line 4: //: is a directory

Trying to check the version with python3 --version returns the same thing

The error appears to happen randomly, it was not happening for a while (after installing python3.10 and then later python3.11 again), and then randomly started happening again one day
