Testing branch has this kernel, so to test if your issue is solved you could switch and switch back.
Since you are able to find this specific issue and link it you look capable to solve any issues.
I’m not entirely sure, but since you have snapshots and timeshift setup the rollback should be easy, it is in de default installation so it is deemed stable. I’m on ext4 so cannot advise on personal experience.
Those tuxedo laptops look real nice!
