I don't know how to solve it, because I don't have enough experience and have never encountered such a problem.

Answer 1

[Error] Call to undefined function Bitrix\Main\DB\mysql_connect() (0),
php version 7 is on home?
If yes, make a database connection as it is written in the docs

Answer 2

Fatal error: Call to a member function IsAdmin() on null in C:\OP\OSPanel\domains\ZG1\bitrix\modules\bxmaker.geoip\lib\manager.php on line 362
