Then the computer crashed. Here are the computer specs.

Operating System: Ubuntu 22.04.2
Kernel: Linux 5.15.0-76-generic
Architecture: x86-64
Hardware vendor: HP hardware model: HP Pavilion Laptop 15-cs0xxx

How can this be stopped, o at least what is causing this?

Operating System: Ubuntu 22.04.2 LTS Kernel: Linux 5.15.0-76-generic Architecture: x86-64 Hardware Vendor: HP Hardware Model: HP Pavilion Laptop 15-cs0xxx Right, here is the computer and that 7 year old bug was the closest thing I could find on my own. Since I don't think that's the problem I came here.

Do you need help to file a proper bug report? ...or what is the question?

This isn't a kernel bug, this is a isolation stuff - and the snap sandboxing is doing its job. Brave and other applicatoins don't *need* access to CPU and IO datasets and stuff, and that's not a kernel *bug* that's just an audit alert from apparmor.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
