As of 4.26.1 the engine finally has resolved the majority of the Instanced UObject bugs.
This means that grip scripts are finally about as stable as I wanted them to be with far less (or no) workflow issues.
This is actually a very significant fix to come down in a hotfix and not in a primary engine release.
While there are other issues with 4.26 and you may not want to upgrade at this time, it certainly brings the future releases of the engine into a better light going forward.
It also fixed inclusive nativization of the example templates BPs.
