Yendif Player

I've just installed Yendifvideoshare in a new Joomla 4 site but when I select it in the component menu I get the error:
count(): Argument #1 ($value) must be of type Countable|array, bool given
This is J4.2.5 using teh ATEM template on the backend and RSjuno on the front end

I have double-checked this by installing a fresh Joomla instance after reading your post. But, I do not see any error message here in our local deveopment environment.

Kindly send us your site admin access details here yendifplayer.com/support/contactus.html . So, we could able to get a clue about the issue and get you a fix accordingly.
