Read access exception during vector allocations on ImGui::Render()

[ProjectHSI]

I know I'm doing something wrong, but for some reason on ImGui::Render(), a vector allocation during EndFrame (L5414) goes wrong and I get the error of "Exception thrown at in : 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF."

• I don't see any logic errors in my code that my cause this.
• 0xFFFFFFFFFFFFFFFF doesn't seem to be related to anything (analyzing all the pointers present leads to seemingly valid pointers).
• The disassembly combined with the address suggests that it fails when calling the allocator function.

Is there something wrong earlier in my code causing malloc to fail or is something else happening that I'm not aware of?

I'm using the SDL2 backend with the SDL2-Renderer backend on Windows 10, compiling with MSVC 19.41.34120 (Visual Studio 2022).
I'm also using the (seemingly unofficial) packaged version of ImGui from VCPKG, although this happened before I migrated to VCPKG, so this is unrelated.

Yeah it was an overrun.
