I’ve seen it around writing communities that you should never use “suddenly” or it’s synonyms to describe something happening abruptly — instead you should just jump in and have it happen.

I strongly disagree.
As a writer, you are telling your story to an audience.
While events might take the characters by surprise, sometimes it’s more polite to refrain from punching the reader in the face with a jarring transition.
Words like, “suddenly,” “unexpectedly,” “abruptly,” etc, slow down the transition into the new event, and make it easier to mentally process. So, when you think that the new event comes on too roughly, go ahead and throw those words in. Don’t let random people on the internet tell you otherwise.
Use your own judgment.

Iāve read this too. Donāt use suddenly. I think itās just a redundant tip like so many others one comes across. Use it if itās justified. š
