How to troubleshoot account analytics errors?

Hey, my account analytics is telling me that my website seems to be getting quite a few errors. The URL to my portfolio website (the source of the errors) is https://rikardhallberg.com. Possible reason(?) I know that when I don't use incognito mode and I visit my own website, some of my browser extensions will log errors in the console. I assume that other people probably have similar/other extensions installed that cause errors as well. When I turn on incognito mode, everything is fine and there are no errors. I just want to be sure that nothing problematic is going on that I could fix. Thanks in advance!
