Same error here:
Warning: PHP Startup: Unable to load dynamic library 'php_imagick.dll' (tried: C:/Users/user/AppData/Roaming/Local/lightning-services/php-7.4.1+10/bin/win64/ext\php_imagick.dll (Can't find the module.), C:/Users/user/AppData/Roaming/Local/lightning-services/php-7.4.1+10/bin/win64/ext\php_php_imagick.dll.dll (Can't find the module.)) in Unknown on line 01.1.1d 10 Sep 2019
The module is there. But if you see the syntax in the last folder it uses the “” instead of the “/” for the php_imagick.dll library.
Something must be coded wrong somwhere in Local
