I have searched online for possible solutions, such as clearing my Mac's cache, changing the security setting on Google Chrome to minimum, checking I have the latest update for Chrome and my Mac to no avail.
I have also received the "oops" message a few times this year on my Mac, though I was able to keep working after it occurred.
If the pop-up message includes space for you to identify what you were doing when it occurred, etc., we encourage users to complete and submit the form so that our programmers can better determine what the issue is and how to address it.
See this help article for troubleshooting steps for Mac issues.
If you confirmed that you have all of the minimum system requirements, you might also try clearing your cache and cookies.
