You ward a creature within range. Until the spell ends, any creature who targets the warded creature with an attack roll or a damaging spell must succeed on a Wisdom saving throw or either choose a new target or lose the attack or spell. This spell doesn’t protect the warded creature from areas of effect.
The spell ends if the warded creature makes an attack roll, casts a spell, or deals damage.

I don't think the 2024 version of this spell has received any errata so far. At least, there's nothing listed for it with the other spell errata here.
Are you talking about the difference between the 2014 version and the 2024 version — how the target casting a spell now ends the effect? It doesn't have a whole lot of impact on the Spirit Guardians technique because you can just cast that spell first.
The case is carried over.
If the warded crea-ture makes an attack, casts a spell that
affects an enemy, or deals damage to
another creature, this spell ends.
Spirit guardians isnt summoning another creature. you are the source of the damage.
Yes, I agree. That has always been the intent of how this spell should work. The change made to the 2024 version doesn't affect this case, though, since all it does is change "casts a spell that affects an enemy" to "casts a spell".
