Go to the bootstrap.min.js file in the zip file and replace your old bootstrap.min.js file in your website with this new one and it will work fine with jQuery version 3 or later.
Many thanks, this easily sorted the error!
I guess all files from zip should be replaced not just bootstrap.min.js.
It fixed my problem, so thx a lot!
Thank you so much! Worked.
