Hello, and welcome to the community.

With the information you have provided, I am only able to offer you a broad answer.

The Error: Assertion failed: InTexture != nullptr
The Location: …/Engine/Source/Runtime/Engine/Private/UserInterface/CanvasItem.cpp] [Line: 382]

Checking the engine source files using the location, you can get a hint at what failed.
“SetColor(InColor);
// Ensure texture is valid.
check(InTexture != nullptr);”

It looks like this may be due to a texture with a null value. I would check any widgets, materials and material instances. If you deleted any assets, see if any old references are still in use.

Feel free to provide any additional information in your replies.
