Well my 2022 suburban with 19000 miles left me on the side of the road Sunday. Driving home engine just quit. Called roadside assistance and tow truck came and was able to get it started and on truck. Guy had a scanner with him and hooked up truck and said code was P129f which says was fuel control module lost signal. At dealer now waiting to hear back. At least it is not lifters.

There was a recall on this - https://static.nhtsa.gov/odi/rcl/2021/RCSB-21V739-5556.pdf
Recall only mentions '21 models, but yours is not the first '22 I've seen also had a fuel pump control module go bad.
Seems like it's isolated to a bad batch of parts and no more issues once it's replaced.
