How can i allow access to subdomain in .htaccess? - .htaccess

Question

i have 2 websites, 1st is Main domain: www.ntech.ge and 2nd is Subdomain: crm.ntech.ge
On main domain i have uploaded website files and there is located 3 .htaccess files.
1 Location: Public_Html
1 .htaccess file:
RewriteEngine on
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
RewriteCond %{REQUEST_URI} !^public
RewriteRule ^(.*)$ public/$1 [L]
2 Location: Public_html/public
2 .htaccess file:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Send Requests To Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
3 Location: Public_html/vendor\phenx\php-font-lib
3 .htaccess file:
#deny from all
Main Domain isn't working without those .htaccess files, because i tried to delete it and it won't work. i want to put something in this code to allow access everyone on subdomain and also allow access to main domain.
Thanks.
