They are not until C++23 (See PR 107687 for the status on that).
This is just a diagnostic issue. add constevalue like this to the reduced
testcase allows the testcase to work:
auto t = [](const auto... args) consteval {return test_class(args...);};
Note the original testcase still has issues even if you add consteval to the
lambda and I suspect because std::apply still has issues ...
