I was watching a documentary called Expedition Mars: Spirit and Opportunity (It's really good, I recommend it, you can find it on Disney+) and it said Spirit lost control of its frontmost right side wheel, how did this happen? was it a dust related issue, a age related issue, or a power related one?

No explanation has been established for the wheel failure, although a motor brush failure is one possibility.
