[Closed] Migration from bedrock/composer

Background of the issue:
We're struggling to migrate our Bedrock/Composer based website which uses WPML to standard WordPress. While we have all the plugins and files running now, when we try to migrate the database we are receiving the following error: Fatal error: Uncaught InvalidArgumentException: item should be a Collection or an array or an object in C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlfpcoreObj.php:112 Stack trace: #0 [internal function]: WPMLFPObj::WPMLFP{closure}(NULL, 'setup_complete', false) #1 C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlfpcorefunctions.php(152): call_user_func_array(Object(Closure), Array) #2 [internal function]: WPMLFPObj::WPMLFP{closure}(NULL, 'setup_complete', false) #3 C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlcollectsrcIlluminateSupportTraitsMacroable.php(56): call_user_func_array(Object(Closure), Array) #4 C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlfpcoreObj.php(90): WPMLFPObj::__callStatic('propOr', Array) #5 [internal function]: WPMLFPObj::WPMLFP{closure}('setup_complete', false) #6 C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlfpcoreObj.php on line 112. As this is a WPML error I'm hoping you can give us some insight into how to fix this so we can move our website off Bedrock.

Symptoms:
Fatal error: Uncaught InvalidArgumentException: item should be a Collection or an array or an object in C:MAMPhtdocsvanillavpwp-contentpluginssitepress-multilingual-cmsvendorwpmlfpcoreObj.php:112

Questions:
How can we fix the InvalidArgumentException error during the database migration?
Are there specific steps to migrate a Bedrock/Composer based website using WPML to standard WordPress?
