VST3.7 VSTGUI4 plugin using CBitmap crashes on non-development computer

Developer VSTGUI
1

I use VST3.7.11 (VS2022 Cmake Win11) to develop plug-ins, and everything works fine on the development computer. When I packaged the plug-in and ran it on another Win11 computer which did not have a development environment for c++ and vst3, my plug-in will cause DAWs to crash (Reaper, Bitwig Studio …). I have tried other commercial plugins they all work fine on this computer, so it’s not a problem with the system environment or host software.

I tried to locate the problem and found that CBitmap caused the crash. When I initialize a CBitmap, such as:
CBitmap bitmap1(“menu-down.png”);
CBitmap bitmap2(CPoint(10, 20));
This line of code will directly cause a crash. Other VSTGUI control elements are all fine.

My controller initialization process follows the SDK method:
MyController : public Steinberg::Vst::EditControllerEx1 → initialize → createView → init VSTGUIEditor → open → new CFrame
There is no crash on my two development computers and the bitmap can be displayed.

I can’t set up development environment on that machine because the crash situation possibly not happen again. If anyone could tell me the possible reasons for this error I would be very grateful

I continued debugging the code and found that the line that caused the crash was:
vst3sdk\vstgui4\vstgui\lib\platform\win32\direct2d\d2dbitmap.cpp
bool D2DBitmap::loadFromStream (IStream* iStream)
source = converter;
When we assign IWICFormatConverter* converter to IWICBitmapSource* source, the crash occurs. The converter is not nullptr, the converter->Initialize has been finished
