I saved some WLP037 slurry for an Irish Ale I was planning to make next week. I forgot to release the pressure and when I checked on it yesterday the container was pretty swelled. I released the pressure and put it back. It was saved from two batches of Brown Ale so there was a good amount of yeast in there.
Did I just kill them all by death by pressure?

Your yeast should be fine. Make a starter to rouse it and you’ll be good to go.
As far as I know (which isn’t much) the yeast shouldn’t be able to produce enough pressure actually kill themselves.

Making a starter or at least taking a sample and making a small starter to check the viability of the yeast is a good idea.
Pressure can kill yeast, but not the pressures that brewers encounter.
