I have also faced similar variable addressibility issues while using code generation. This happens while trying to use non-scalars (including arrays and structures). Lookup Table block requires Table Data and Breakpoint Data expressions to be addressable (i.e. the generated look-up function takes both parameters as pointers). If the expression is not addressable, code generation errors.
I do not have a workaround for this but the issue is not reproducible in R2024b. Kindly upgrade your MATLAB to the latest version.
I hope this resolves the issue!
