I can’t relate on the career directly, but I went from call center tech support to manufacturing and it was the best decision I ever made. I knew the job I was in would simply never bring a day of joy to me and money doesn’t do much for that.

The real answer is that you won’t know until you take a leap of faith. I was also terrified I was making a poor decision when I switched, but now I use far more of my skillset and I’m far more engaged as a result.

It may be a complete failure and you’ll have to switch again, but if you’re unsatisfied with what you’re doing, the only way to improve it is to make a change.
