Checkf triggered (crash in builds that have no debugger attached) on launch

[samaursa]

Hi!

Recently added Rive UI plugin to our project for evaluation and encounterd a checkf that is being triggered on Editor launch.

No changes to the plugin and using the latest on main with CL#6f867ee with Unreal Engine 5.4.1 (from github).

My recommendation here is to evaluate on a stable branch. I haven't been able to reproduce this issue on 5.4.1-release.
