If you run bash with the "-o igncr" option, it will ignore extraneous
carriage return characters.

But the characters are there in the first place because your
script has been converted into using Windows line endings:
carriage return + linefeed.

You didn't say how the script was transferred, but lots
of programs could add returns when you transfer something
to windows: git or ftp just to name a few.

You both could try running "bash --version".  The first line should
say something like
"GNU bash, version 5.2.15(3)-release (x86_64-pc-cygwin)"

Note the "pc-cygwin" at the end.

HTH,
