Yesterday we found a toast ring with a fracture in the big ring. It
appears to completely through the ring. Has anyone else had this
experience?

Yes.
Quite a long time ago, 15 years.
We subsequently retired the fractured Tost to the ground towing rig
for moving the gliders from tiedowns to launch and back. It is a very unusual occurence but was easily apparent from the loss of the clean 'ping' sound as they jingled around together. The sound was 'flat' and dramatically different, which is what led to discovery before complete failure.

So yes, preflight ALL the equipment. Don't settle for a line helper just waving a rope end or ring in front of the glider for your first daily launch.. How's the length of the back splice? How's the bulge of radius change at that point - frayed? Tape wrapped to be invisible? That transfers the wear point to the head of the tape. Look there, too.
Be thorough, be safe.
