I've been using Opera GX for the past few days on my desktop and I've run into an issue- for some reason, my computer will not go to sleep anymore. According to powercfg/requests in Command Prompt, the issue is that apparently my computer thinks that audio is playing, so it won't go to sleep. It only seems to be when Opera GX is open, though. Running on Windows 11.
Also, I feel I should mention that I've also downloaded Opera GX on a separate laptop around the same time and have had no audio issues with that computer.
