Why don’t you get a shark vacuum cleaner. Honesty those make vacuuming kinda fun( it even has headlights!). You can stick some headphones on, listen to some music you like, and you even get some exercise! And you can still vacuum when the WiFi goes out!
Now if you’re disabled or something I understand the need for a robot, but otherwise you could save a ton of money, get exercise, and have zero privacy concerns.
If you want something that’s under £100 and don’t mind Bluetooth check out the soundcore life Q30s.
Honesty the first time I tried them I though they cost double what they actually do, and they’ve been my daily driver since.
For some reference I also have some audio technica ATH-M50Xs, but I find these more musical and they have ANC so I daily drive these and use my M50Xs for critical listening when needed( I’ve added that just so you know that I know what decent audio sounds like and don’t think that cheap beats knockoffs are good).
Could it be that the manjaro repos have older versions of the HIP runtimes then what blender 4.0 is built for? Just a thought. Either way I would report it to the blender devs so they can fix it if it’s a bug
