I think that one of the best forum software available nowadays is: XenoForo. It is not free but their support is amazing, if you get any trouble you their support will be easily sorted out.

XenoForo has the following requirements:

• PHP: 7.0 (PHP 7.4 recommended)
  
• MySQL: 5.5 (MariaDB / Percona also compatible)
  
• PHP extensions: MySQLi, GD (with JPEG support), PCRE, cURL, SPL, SimpleXML, DOM, JSON, iconv, ctype
  
• Common PHP functions must not be disabled
  

They offer a requirements test script to know if your machine is capable of running their product.
