Dropdown not working after updating to version 3.0.1 (conflict with select2)

Hi everyone. I’m having the following issue:
After updating the plugin from version 2.9.15 to version 3.0.1 the ‘Dropdown’ language selector stopped working. If I click in any of the languages of it, nothing happens.
If I change the ‘Widget Look’ in the settings page of the plugin to ‘Float’, it works perfectly.
The problem is related to select2.js because I have a javascript as follows:
$(".language-selector select").select2({
minimuResultsForSearch: Infinity,
containerCssClass: "language-container"
dropdownCssClass: "language-dropdown",
});
If I remove this thing of select2, the dropdown works perfectly, so I think it must be a conflict between the new version of the plugin and select2.
Thanks.
