Text fields unresponsive despite working keyboard input elsewhere

Actions through my keyboard are translating into movement based on my keybinds. However, all input into text fields is bugged (chat, world naming, signs, creative inventory searches, etc.). It’s like the text fields specifically can’t “see” my inputs, despite the rest of minecraft not having any issues. In the attached image, the text field appears to be active and ready for keyboard input, but nothing goes through. This has been an issue for about a month (since the 1.21.1 update) and has presisted through each hotfix since then. Some solutions, like alt+tab-ing, have granted temporary fixes, but even this has stopped working and I now cannot type at all. I have no contollers connected, weird windows settings pertaining to the keyboard, or anything else unorthodox I would expect to cause issues like this, and I’ve seen others complain about similar issues in online forums since the same update, including here in the official bug reporting website. I’m at a loss at this point :/
