Crashes
I wasn't able to reproduce the crash.
Assuming this to just be a reporting issue.
from scala3.

Ah, right. There's no crash, but the code fails by throwing an exception at runtime when run as a script.
// repro-script.sc
sealed trait T_A[B]
sealed trait T_B[C]
case class CC_B[C]() extends T_A[T_B[C]]
case class CC_C[B, C](c: T_A[B], d: T_B[C]) extends T_B[C]
case class CC_E[C]() extends T_B[C]
val v_a: T_B[Int] = CC_C(null, CC_E())
val v_b: Int = v_a match {
case CC_C(_, CC_C(_, _)) => 0
case CC_E() => 5
}scala-cli run repro-script.sc

Very similar issues which were reported together with this, potentially duplicates:
