The “graphics context” refers to a collection of information related to the current state of the graphics pipeline, such as the active shaders, render targets, and other parameters.
The error you’re encountering, suggests that the engine is trying to issue a GPU command, but there is no current context established. This error often occurs when you are trying to perform rendering operations outside of the normal render thread, or if there is an issue with the way the engine is switching between different pipelines.
To resolve this issue, you may need to investigate the code or assets that were changed or added during the upgrade from Unreal Engine 5.0 to 5.1, as that may have introduced the problem. You may also want to look into the engine’s log files or enable debugging features to see what exactly is causing the missing graphics context error.
