I posted this in the Playstation Studios OT, but I guess it makes more sense here now.
I was curious to see how many other games this might apply to, and if you do a Google site search on the Playstation store for that specific wording around 'unexpected behaviour or errors', you currently get around 100 games:
Some notable names in there, but without knowing what 'unexpected behaviour' or 'errors' we're talking about, it's hard to know how deeply individual games might be affected. Viewing it optimistically, some of these smell like possibly online service issues (e.g. the older MLB/NBA games). A number of VR games are in there too.
....welp, Sony has some explaining to do.
