For the past 2 weeks, I've experienced a few Kernel Panics. When looking at the crash logs, it specifies that there was an assert fail, containing the following information: panic(cpu 1 caller 0xfffffff00bb5c154): ANS2 Recoverable Panic - assert failed: [14083]:low wA f4 i1875522 s3180082 n16 d0 w1.6 tGC9 tL30, d:0x22401, a2:0x2890041, a3:0x60000000 - power(13). I noticed it usually happens when I am performing a lot of Memory and/or CPU intensive tasks, though I don't know if there is there is any true correlation between the two. Does anybody have an idea that the specific assert means? The following link is to a pastebin with the entire crash log: https://privatebin.randomserver.xyz/?fb94ef9e6656eb9f#Ah5qpzLErBk1ZqM4egsbnqGtTaPZnokx3dQoJHdoppbJ

Edit: I'm using an Intel MacBook Pro (2019), running macOS 12.5 (Monterey)

Unfortunately, no-one - except Apple developers with access to the source code - can tell you what that specific assertion means.

However, I can tell you that it is related to the storage subsystem on your MacBook Pro. It is likely to be a hardware error.

I would check and double-check that you have backups of the device - and then contact Apple support with this issue. Hopefully it is an issue that can be verified using hardware testing tools, so you can get the computer repaired.
