Describe the bug

On Kotlin-1.6.10 everything was working fine
but after I upgraded to Kotlin-1.8.10 tests started failing randomly with below exception
ut version - org.jetbrains.kotlinx:kotlinx-coroutines-test:1.7.2

kotlinx.coroutines.test.UncaughtExceptionsBeforeTest

Provide a Reproducer

Create a project with kotlin 1.6.10 and test version 1.6.4
upgrade to kotlin 1.8.10
tests started failing

It means that your tests throw exceptions after they finish, in forked-off coroutines. We used not to catch such exceptions, but now we do, so that the tests are more robust. See the discussion under #1205 This functionality can be disabled with #3736 (comment), but it's recommended to fix the tests instead.
