proxy_fcgi:error AH01071: Got error 'Primary script unknown, Apache + PHP 7.3.2

Question

I'm using my companies Docker Template to try and connect to Localhost, but I get the message "File not found" when inputting localhost:8888 into chromes URL bar. After running the command "docker-compose up"in Git Bash, I try to connect to Localhost, but apache gives me [proxy_fcgi:error] AH01071: Got error 'Primary script unknown. I'm not sure why this isn't working because I'm using the companies documentation through this process and the documentation worked for all of my other coworkers. All the containers in docker seem to be running correctly, so any help with the apache side would be appreciated

Some fixes I've tried:

Editing my .htaccess file, as of right now it is:

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews -Indexes
</IfModule>

RewriteEngine On

# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ./index.php [L]
ProxyErrorOverride on
</Proxy>
</IfModule>

Editing my apache.conf file, as of right now it is:

ServerName localhost

LoadModule deflate_module /usr/local/apache2/modules/mod_deflate.so
LoadModule proxy_module /usr/local/apache2/modules/mod_proxy.so
LoadModule proxy_fcgi_module /usr/local/apache2/modules/mod_proxy_fcgi.so
