To be fair, the pandemic caused delays and potential materials/labor increases. It was not the actual cause of Harmonious' failure and having to spend even more to create Luminous, cancelling the Table for CommuniCore Hall, lighting fiascos, cancelling PLAY!, poor storytelling in Guardians, cancelling SEE (which was probably a blessing), etc.
It played a role on the timeline, no doubt - and you can't rebuild demolished buildings. But, Disney created many of it's own issues with the EPCOT redo that have nothing to do with the pandemic.
Now back to Mistake on the Lake: The Residences.
