Navigation Menu does not work in mobile

Hi there, my website navigation menu does not work when viewing from mobile. The top black menu won’t drop/expand when I click.

When I view from desktop during expand mode, the menu obviously works. When I view from desktop and I resize the screen so it has the same size as mobile browser, the menu works.

Only when it is in mobile it does not work.

My WP version is 5.7.1
The i-excel theme version is 1.7.6
PHP 7.4

I recently upgraded my WP version and ever since the navigation does not work in mobile. I can’t downgrade as there have been some other data added since. Any help would be greatly appreciated.

When I load the page and inspect the chrome browser of my mobile browser (via USB Debugging), I got the following errors. I don’t think it is related to my navigation problem. But I include the errors regardless
