In the simulink window go to Simulation -> Model Configuration parameters, in the solver tab -> Solver options, try using 'variable step' and select 'auto' in solver. Also you can reduce the 'relative tolerance' in 'Additional options' to 1.0e-4 or 1.0e-3 and check if the error resolves.

Unfortunately, this doesn't work for me

Some times changing "solver time constant" or "solving method" could be effective.

Thank you, I'll try this

Try scaling your variables
