Can switch statements cause a 'Query is too Complex' error in MS Access 365? - sql

Question

As background, we are currently using Lotus Approach as our job schedule database. Out of fear that one day it'll cease working with newer versions of Windows, I've been searching for an alternative that isn't terribly dissimilar from Approach. One of the features in Approach that has been wonderful is that calculated fields are stored in the front end and has full access to all tables in the database, as well as other calculated fields without having to link them to forms, reports, or each other. I have yet to find a program that handles calculated fields in a similar manner, so I've moved to using queries in Access to beginning building these calculated fields (around 200 formulas).
That said, I have 4 tables and 3 queries, but I'm hitting a wall with one of the queries. In the query that's giving me the error, I think I've determined the problem has to do with 1 switch statement (AUDIT_JTD_EARNED_REV) as there are 3 other formulas that rely on this calculation and if I delete one of these (not all of them), then the query will run.
I have not used Access before in any meaningful way, so if there is a better way of doing it, then I'm all ears. Below are the 3 queries I'm using and the error is occurring in the Audit Calc query.

The deepest nested IIF in all of these is only 3 deep and the most complex Switch statement only has 4 options. And the fields used in these statements are not overly complex, either. I've been fighting to simplify this for about a week and don't believe I can make it any more concise.
Thanks in advance.
