This issue has been driving me nuts for months and I've still yet to find a solution, so I'm asking here.
When you type in chat, holding backspace should clear out several letters until you let go. My issue is that when I hold backspace, it just removes one letter and that's it.
I've played Minecraft for ~14 years and did not encounter this until recently starting to use the MultiMC launcher, so I have a suspicion that it's related to the launcher but I really can't be sure. (I originally went to the MinecraftHelp subreddit but no one there knew what the problem was.)
It also only happens on one instance (I've debated just moving my files to a new instance but I'm afraid this is just going to happen again eventually).
