error: The SAT solver timed out while solving the problem.
Consider increasing the timeout with the `timeout` config option.
If solving your problem relies inherently on using associativity or commutativity, consider enabling the `acNf` config option.

error: None of the hypotheses are in the supported BitVec fragment after applying preprocessing.
There are three potential reasons for this:
1. If you are using custom BitVec constructs simplify them to built-in ones.
2. If your problem is using only built-in ones it might currently be out of reach.
   Consider expressing it in terms of different operations that are better supported.
3. The original goal was reduced to False and is thus invalid.
