I have noticed that you are using 0.0005mm thickness for the spiral conductor. If possible, I would recommend you define it as a sheet. This will simplify the geometry and the computation would be much faster. Also, this approach would not decrease the accuracy of the results.
If the above approach is not possible, then try to assign mesh operation. More information about this can be found here - Ansys Electronics 2022 R2. Alternatively, you can go through "defining mesh operations" chapter in the HFSS help pdf document.
