Opening courses on Moodle 4.3 or 4.4

[leehamgold42]

HI, I have use the snap theme for a long time now and I updated my moodle to 4.3 as I saw that there was an update, However when I go to access a course I get "
Fatal error: Declaration of theme_snap\output\core\course_renderer::course_section_cm_completion($course, $completioninfo, cm_info $mod, $displayoptions = []) must be compatible with core_course_renderer::course_section_cm_completion() in /home/hpscloud/public_html/moodle43/theme/snap/classes/output/core/course_renderer.php on line 292"

How can I resolved this? I have gone back to my previous moodle version of 4.1.1 with snap 4.1, and it's broken
