Chorus, Modulators & Statefulness,Exception thrown: read access violation. _Mem was 0xFFFFFFFFFFFFFFFF

Hello everyone,im new to JUCE framework and it is really difficult for me to work with it alone that is why i bought a "very good" Outputa course.
And i stucked on the fourth session " Chorus, Modulators & Statefulness".
Their code just doesnt work and i need chatGPT,my low quality skills and this forum to fix their mistakes all the time but now i dont see anyone who has the same problem as me.
I see this error every time i debug the project.

That’s not the real spot in the code where the bug is, that is where the code execution ends up finally crashing due to problems elsewhere in the code. We need more information about your code, for example the call stack leading to the crash would be useful.
