Lego Rock Band "Access violation reading location 0x14 (unmapped memory)" issue

I've been playing Lego Rock Band on RPCS3, and at the final stage, the Wembrick Stadium. After the custcene plays, I get this Access violation reading location 0x14 (unmapped memory) error. I admit my PC isn't the greatest. But I figured it can run Lego games. My PC specs are an Intel Core i7 (9th gen) CPU. An Nvidia GeForce GTX 1060, with 16 gigabytes of RAM. Any help? Do Lego games/Rock Band games need specific settings? Any help would be appreciated.
