It might be a potential bug and I will confirm this with the engineering.

1) Run Analysis & Synthesis ->RTL simulation Passed.
2) Run Analysis & Synthesis, Then Run Fitter -> RTL simulation Error.
3) Run Fitter directly -> RTL simulation Passed.

Case (3) is particularly interesting as it works after fitter stage. I recommend avoiding situation (2) as a workaround.

FYI, in cases where this error arises in Quartus Standard, we can only provide a workaround unless there's no available solution.

Thank you for your understanding.
