Rock Band 2 [BLUS30147] Access violation 0x8 (unmapped memory) after playing songs

Hi, I've been using RPCS3 and playing Rock Band 2 on it for a long time and it works great! I've actually got the "Deluxe" mod by MiloHax on it and the 60FPS venues look gorgeous. However, I've been getting this error frequently and it makes my game crash.

Thread (main_thread) [0x005c35fc]} VM: Access violation reading location 0x8 (unmapped memory)

It usually happens after completing a song and leaving the score and results screen. The game will save and then return to the song selection screen, but after a second or so, the game will crash and show me that error. It can happen after playing as much as 5+ songs, or it can happen after just one song. It can also happen when transitioning between menus, like from song selection to character selection, leaving mid-song from the pause menu to the song selection screen, or even in tour mode from the world map to the practice space menu.

Here are my specs:
SYS: RPCS3 v0.0.28-15360-30a5d646 Alpha | master
- SYS: AMD Ryzen 5 5600G with Radeon Graphics | 12 Threads | 15.38 GiB RAM | TSC: 3.893GHz | AVX+ | FMA3
- SYS: Operating system: Windows, Major: 10, Minor: 0, Build: 19045, Service Pack: none, Compatibility mode: 0
- SYS: Current Time: 2023-07-16T21:20:54
- RSX: Found vulkan-compatible GPU: 'AMD Radeon RX 6600 XT' running on driver 2.0.270
- SYS: Firmware version: 4.89

And in my attached log, the following instance was after playing about four songs individually (not in a setlist) in Quickplay mode.

Do not use SPU Block Size Giga, that is mostly unusable and just there for debugging.

I've changed the SPU Block Size to Safe, and it's still giving me the same error. There's the log with the change implemented.

I'm not sure what could be the issue then as nothing else looks off, can you change your settings back to default and only change what is the wiki page for the game?

Also, test without the mod, as we don't offer support with mods, that could be what's causing issues.
