Bash Version: 5.2
Patch Level: 9
Release Status: release

Description:
   If the interpreter after #! is wrong, a non-informative message prints

Repeat-By:
        "unix2dos bashscript" starting with #!/bin/bash
        ./bashscript
         bash: ./bashscript: cannot execute: required file not found

         Before version 5.2:
        ./bashscript 
        bash: ./bashscript: /bin/bash^M: bad interpreter: No such file or 
directory

Fix:
        Probably some code has to be moved in execute_cmd.c
