How to eliminate the conflict between Google tag manager and scripts on the site?

Question

Google

I inserted the Google tag manager code, galleries and pop-ups stopped working correctly, I tried to use the "Google Tag Manager for Wordpress" plugin and got the same result, it gives such errors and the galleries do not work, the site itself , the theme of the site , I don't know what is the reason and how to do it right insert the Google code so as not to break everything, I don’t even understand this closely, so if there is a solution to the problem, I would have a simpler instruction.

How do you have jQuery connected? It looks like your error is due to the lack of jquery on the site...
