However, while it sorted it self, should I be seeing a simple plugin in this menu? Its sitting at the top above Unreal Engine. Clicking it leads to error
when clicked this happens.
HDRI Browser should not be sitting in menu above, nor should it be trying to open. Its a plugin to be used from inside UE5.
Hope that helps and hope you can fix these bugs and errors.
8 months later, still not fixed 
Come on please, can we have a fix for this ?
I have the same problem.
So the same Epic that still didnāt adress these issues is talking about releasing UE6 and deprecating blueprints?
MD-0011-0, II-E1003, IS-0009, IS-EO-Plat-NoFnd:Win-2
Fix found: Download an older Epic Games Launcher. 18.000 and below.
My issue with this has been persisting since November 2025ā¦
Still no solution.. I gave up on Fab about this.. really bad support.. Also opened a ticket for this months ago and got not a single answer from them, yet.
only a post here in the topic about āteam is investigatingā and a workaround, that does not help..
Yes.. I am writing since November.. and never tried to wait for syncing to finish.. or re-sync multiple timesā¦ 
Even tried reinstalling the whole Launcher and deleting all the caches and the vault Data..
Cleaning up my whole Epic System..
Nothing works.. and Fab Support.. is silent..
This is 100% absolutely on their end, I donāt think thereās much you can do.
Iāve faced all these errors MD-0011, II-E1103, IS-0009, IS-EO-Plat-NoFndā¦
The only thing that worked so far was installing an older version of the launcher. All issues disappeared. Iām totally backing up my assets and never updating this ā ā ā ā ā ā ā launcher ever again.
