Has anyone here ever lost an entire tank of fish or even one fish from toxic gases in the sand bed?

Nope. It's a myth. My DSB spits out bubbles now and then and neither the puffers nor the banjo cat have suffered visibly in any way.
you would literally prob have to leave the sand untouched for months maybe even years for it to ever reach that state. depending on your tank and fish size sometimes fish sift through the sand and move it enough to release it, and weekly water changes/gravel cleanings help tremendously.
another way to have that much toxic gas under the sand is to have such a deep bed of sand and you would have to bury alot of food under it. and again leave it untouched for a long time.

I'm letting mine get clogged and anaerobic on purpose. So far nothing bad has come of it. I read it takes about seven years to actually become a hazard and all the time before that it just destroys nitrates for you.
I've had sand in my 75g tank for many years now. It's been disturbed on occasion, but I don't stir it up purposely. I have never lost a fish. Tank has gone from various Cichlids, Perch, Catfish, Characins, and Plecos.
Ditto, I had a 125 with 2-3" of sand & a couple hundred pounds of granite boulders sitting on top of a lot of that sand for several years, & never had an issue. Even when removing all of those boulders I left my fish in the tank (I was tearing it down & selling the fish) and had zero issues with any type of toxic anything. IMO it's a non issue.
