I was creating hand-tracking functionalities in Unreal 5.2 but when I tried to migrate the project into 5.3 I got these errors preventing me from doing so:
When using third party plugins (in this case MetaXR), you have to either wait for the plugin to get updated to the latest engine version, or try and recompile it yourself. In this case I know recompiling won’t work, so you’ll have to wait until Meta updates the plugin.
Since Nov.8 they offer MetaXR plugin which supports 5.3.1 which should resolve your issue.
AFAIK version mismatch between plugin and editor will prevent the editor from working properly. I recommend you to match the version as strict as possible.
