What happened?

I am running Minecraft in single-player mode locally. I’ve been experiencing intermittent disconnections, occurring at least once a day, which occur whether the game has been left running idle or while actively playing. These disconnections have occurred sporadically over the past few weeks, sometimes while interacting with inventory-related actions such as opening a chest, accessing the AE wireless terminal, or similar tasks. There is no visible crash or crash report associated with these events. I updated the modpack to the latest version yesterday, and the issue is still occurring.

This same error was found in the FTB Presents Direwolf20 1.21 modpack:
Disconnect with "Failed to encode packet 'clientbound/minecraft:set_equipment'" #603
