Cannot start deployment - 'algo' file not reading properly.

[CMealings]

I've reinstalled Windows 10 and as a result am reploying an algo server I've had for a few years.

I've installed Ubuntu 20.04 (WSL), Python 3.8, and all the dependencies without an issue.

The problem comes when I try to start deployment.

(.env) cmealings@DESKTOP-2OEIIN0:/mnt/c/Users/charl/algo$ ./algo
./algo: line 2: $'\r': command not found
: invalid optionset: -
set: usage: set [-abefhkmnptuvxBCHP] [-o option-name] [--] [arg ...]
./algo: line 4: $'\r': command not found
./algo: line 18: syntax error near unexpected token ``$'in\r''
'/algo: line 18: ``case "$1" in``

I feel like this is a really simple problem, the contents of the 'algo' file or another script it call just aren't being read properly, as if it's being read by the wrong application. Help?
