Anybody get the new 662.40 update? Notice any difference?

So my issue started out with this error (pic attached). Took it to my dealer expecting it to be potentially a SW update. Two brake boost assemblies later, it sounds like my 2025 SEV LT faults out when they try to bleed the brakes. They put me in a loaner, 2026 Hummer EV with no complaints, but it's been 5 weeks now. GM seems to not have been able to solve it. Has anyone else run into this problem? Is it more than just my SEV and is it nationwide?

Thanks for any help on this in advance.
