Help: Character errors in the interface

Hello. Today when I first opened the app I noticed the characters displayed in the desktop version o Anki had a bunch of errors, specially missing errors. I didn’t notice any error in the display of cards, but the browser is barely usable, making it really hard to add new cards for my classes today. Any idea why this could be happening? The last add-on I installed was Customizable sidebar, but I can’t even identify it in the add ons screen to try and suspend it. My desktop Anki is version 2.1.34 (8af8f565).

I’m not sure if the image will be correctly uploaded here, so here’s another option to visualize

Nevermind, restarting my computer solved it.
