When the mouse clicks on the imgui interface, an error message appears: Exception thrown: read access violation.**window** was nullptr.

When I clicked the imgui interface with the mouse, an error occurred; it prompted me Exception thrown: read access violation.windowwas nullptr.; I checked the error stack and found that the ImGuiButtonFlags_NoNavFocus macro definition was executed and ClearActiveID was executed. looking through the call stack it happens because the ClearActiveID() function is called，which inturn calls the SetActiveID() with 0 and NULL as arguments ,i.e. SetActiveID(0, NULL)，And this original error occured because in the function SetActiveID

It seems like you forgot to initialize one of your pointers.

can someone tell me is this the Hazel Source? or is it Hazel 2D only? I'm so confused!

[ViktorPopp]

It seems like Hazel2D

I've had a similar issue where i had to remove the window-> part of those 2 window->DC.Layouts
Maybe either try that or update to a newer version of imgui?

I've had a similar issue where i had to remove the window-> part of those 2 window->DC.Layouts我遇到了类似的问题，我必须删除这 2 个window->DC.Layouts的window->部分 Maybe either try that or update to a newer version of imgui?也许尝试一下或更新到较新版本的 imgui？

Deleting Windows presents new problems and can only be attempted with a new version

I removed this loop and it works
