It’s not a fundamental solution, but changing the LoadingPhase of ChooserUncooked in the Chooser.uplugin from Default to PreDefault will prevent the error from occurring. It will likely be overwritten in the next engine update, but I believe this bug will be fixed by then.
"LoadingPhase" : "Default"

{
"Name": "ChooserUncooked",
"Type": "UncookedOnly",
"LoadingPhase": "PreDefault"
},
{
"Name" : "ChooserEditor",
