we've been having this same issue for a couple of months now on a couple of recent versions of cypress - 13.13.2 and 13.15.something
test code is not at fault - some of the simplest and shortest specs fail due to crash while more complex long ones pass

i work with 2 repos and the problem is only in one of them

also behaviour is different on different kinds of environments
on review stages (gitlab ci) the error sometimes occurs but then test passes on retry
on production like stages the same tests fail all the time, retries don't help
in both cases exactly the same error, nothing to do with tests or the app - just a crash

tried changing browser to electron - didn't help
also tried experimentalMemoryManagement both true and false - didn't help
numTestsKeptInMemory is 0
