After Bloqs was upgraded to 4.2.2, I cannot edit any Bloqs custom fields nor create a new field anymore.
When I try to edit any Bloqs fields or add a new field, it returns to the following error message:

Fatal error: Uncaught Error: Call to undefined method Basee\App::configSlashed() in /Users/chris/Documents/Websites/harthouse/_site/system/user/addons/bloqs/libraries/EEBlocks/Helper/UrlHelper.php:109 Stack trace: #0 /Users/chris/Documents/Websites/harthouse/_site/system/user/addons/bloqs/libraries/EEBlocks/Helper/UrlHelper.php(88): EEBlocks\Helper\UrlHelper->getSiteUrl() #1 /Users/chris/Documents/Websites/harthouse/_site/system/user/addons/bloqs/libraries/EEBlocks/Helper/UrlHelper.php(67): EEBlocks\Helper\UrlHelper->getSiteIndex() #2 /Users/chris/Documents/Websites/harthouse/_site/system/user/addons/bloqs/ft.bloqs.php(516): EEBlocks\Helper\UrlHelper->getAction(‘fetch_template_…’, Array) #3 /Users/chris/Documents/Websites/harthouse/_site/system/ee/legacy/libraries/api/Api_channel_fields.php(410): Bloqs_ft->display_settings(Array) #4 /Users/chris/Documents/Websites/harthouse/_site/system/ee/EllisLab/ExpressionEngine/Model/Content/FieldFacade.php(226): Api_channel_fields->apply(‘display_setting…’, Array) #5 /Users/chris in /Users/chris/Documents/Websites/harthouse/_site/system/user/addons/bloqs/libraries/EEBlocks/Helper/UrlHelper.php on line 109
