Q. For 2023 was I a resident of Wyoming or Utah?
A. Utah.
Clearly, you were only temporarily away from your primary residence. This is particularly true, in the case of the absence being for the purpose of attending school. You were not a resident of WY, for 2023, not even a part year resident.
If you had any income in WY, that income is taxable and reportable on your (full year) UT resident tax return.
