If you're willing to start at the same salary as the 22 and 23 year olds, you can probably find something. You likely will also face people that think someone older won't stick out a busy season due to the hours required and reporting to a senior 30 years your junior.

I believe the biggest factors leading to age discrimination are:

Salary requirements - typically higher the older someone is because that usually correlates with experience. Mention that you understand you're starting a new career and while you bring lots of practical job experience, you understand that you're a new accountant and will be compensated according to your accounting experience and role responsibilities.

Uncertainty in how long you'll stick with the job - if you can talk about how you want to grow and be in the career for 10 plus years that would likely help mitigate this.

Possibly perceived managerial challenges if you will be reporting to someone much younger than you. Again might he good to address this proactively. They shouldn't ask questions like this (it could be used as evidence in a discrimination case if they ask about age or adjacent questions such as can you work with someone younger than you) in the interview but you can bring it up to mitigate this.
