After the Spider-Man update, I am unable to edit any deck that contains red cards or lands capable of producing red mana.

Issue:

Applying the Red color filter in the deck editor does not work. Clicking OK after selecting the red filter does nothing.
Any deck containing even a single red card or a single land that can produce red mana becomes impossible to edit. The deck editor gets stuck on "Connecting to Server" indefinitely.
Decks that contain no red cards and no red mana sources can be edited normally.
The problem occurs on both the PC and Android versions of MTG Arena.
Reinstalling the game does not resolve the issue.
I can still play matches normally with these decks; only the deck editor is affected.

Additional testing:

A deck containing only basic Plains can be edited normally.
Adding a single land capable of producing red mana causes the issue.
Adding a single red card (such as Iridescent Tiger) also causes the issue.
Other players I know are able to edit red decks normally, so the problem appears to be specific to my account.
