Solved for now, I tried an older WordPress version.
Hello,
You can follow these steps:

Or, if you have a Softacolous App in your C-Panel account, you can upgrade/downgrade your website there.
Just try to re-use the latest versions of WordPress that worked for you.
Fixed it.
Plugin editor -> includes -> functions.php
line 1356
change href=”skype:’
to href=”tel:’
and
‘?call”
to ‘”
Everything should work fine.
