I removed the file, MobileDevice.framework, as recommended from the link shared above. It didn't seem to work at first. I changed users to a new admin account and it still would not work. I then ran Etrecheck, but that did not seem to have any benefit but to tell me stuff on my laptop weren't working as well as they should.
I went back into my primary user/admin account and tried Safari again and it "miraculously" worked as normal.
Thanks for the support and I'm assuming the solution. Somewhere between removing the file, changing admin users and running Etrecheck, seems to have solved my issue.
You are welcome. I read Apple has released a new version of iTunes that fixes the problem.
Safari cannot be opened because of a problem.
