I'm *reasonably* certain this is a duplicate of LP: #2009136 as that covers kernel 5.19.0-35. I don't think there *is* a 5.15.0-35, and the "reversion to 5.15.0-67" (which is the current 5.15 release) also suggests that this is limited to affecting the 5.19 releases, not the 5.15 releases.

Anyway, marking this as a duplicate of the aforementioned bug for now but please do correct me if I'm wrong!
