Hello, @gwiezdnewrota,
I see, I have checked your site again now accordingly as you described in your previous reply, and found the issue on your site. And I think you are right as well, that issue is because of the animation as the animation is taking too long to appear/work on your site.
Please try to disable the animation of that block and check back again after clearing the cache.
And your provided WP Admin URL is not working now: https://postimg.cc/CB67bgGV
