At face value, I might suggest reversing that decision, especially as there was no issue with the 575xx driver series (as your inxi output demonstrates).
Remaining with kernel 6.18 (LTS) is suggested if that combination was working for you.
Edit:- I have compiled the following information which may possibly be useful for general reference:
Under Notable Package Updates in the Stable Update 2026-07-11 announcement topic, it was stated that:
When packages are from the main repositories they are sometimes dropped to the AUR. However, all I can find is nvidia-575xx-dkms, in this instance:
It’s important to note that this is by no means a recommendation to use these drivers – only informing that they are available.
I have not found 570xx drivers available via the AUR, at this time. Perhaps @philm or @Yochanan might shed some light on this.
Additionally, under Known issues and solutions (on 2026-05-02) in Issues with updating Kernels due to Nvidia drivers:
Also noted was:
So, regardless, users of Nvidia 570xx, 575xx or 580xx series drivers, appear to be limited to kernel 6.18 (LTS) as it is the last kernel series to support those drivers.
While I have no concrete suggestion to workaround your issue, this information is at least consolidated, in case it may be useful.
