Gigasliders don’t load anymore

Since a few days the gigasliders on my website don’t load anymore. All I see is a continuous wheel indicating there’s something loading.
I run the latest version of WP (5.5.1), all my apps are up to date. I cannot find any other mention of this problem on the internet so I’m hoping you can help me.

Thnx! Joris
