Error when trying to upload new version of game on the arcade

I am trying to open the 'Upload New Version' page of my game Tag on the Arcade. When I press the button on the sidebar, I get redirected to an error page with the standard message:

"Unexpected Error Whoopsie daisy! Something went wrong with your request. Don't worry, this isn't your fault and the error has been recorded on our systems. An engineer will look at the report soon."

I have had this issue for a few days now for the past week and did not manage to get through. Does anyone know what's up with this? If it's relevant, Tag was made in C2 and the version on the arcade hasn't been updated since october 2019. That's one of the main reasons I want to see if I can update it.

Bumping this because the issue is still the same after a month! Tag is the only game I have on the arcade that I can't upload a new version of. I'm kind bummed out that I can't give updates to one of the top games on the arcade.

Still having this issue. Ashley Tom any chances that you will look into it?
