How do you deal with travel hiccups that affect flights & hotel/Airbnb stays?

Hey all, I’m still new at this solo traveling thing, and while my previous trips have worked out for the most part, an upcoming trip to Seattle next week seems like it’ll be more rocky. I planned to center my trip around a concert that’s just been postponed . I booked my flights but not accommodation . And I’m feeling overwhelmed by it all. It seems there’s not much I can do until I know the new concert date . Thankfully, I booked with an airline that doesn’t have change fees. Budget-wise, I’d prefer to be frugal where possible, but this late, I know I’ll be spending $$$

Seasoned solo travelers, how do you adjust your plans when your planned events go awry? E.g. chosen place to stay can’t accomodate your travel dates, an event you’ve been looking forward to is postponed or cancelled, that sort of thing. Would appreciate any advice you have, general or specific.
