Interestingly I don’t have that problem (yet). Seems like they follow the microsoft updating strategy of forcing the update only on a portion of the userbase first and looking what telemetry comes back.
An unofficial alternative would be to install something like lightcord as an alternative. Keep in mind though that this is not supported by discord.
They actually ban users permanently for using alternative clients. It’s insane. I wish there was a good FOSS alternative that doesn’t use their network and has all the features.
Thanks for the quick fix.
By the way, in case you were curious, a minute or two after I posted, I edited the JSON to trick Discord into thinking it was updated and was able to use it until the update. I had my nuce afternoon chat with my brother!
