Using Spring Tools Suite 4.13.0 (which is based on Eclipse Platform 4.22.0 and JDT 3.18.1000)
When I try to launch a suite using the JUnit 5 test runner (selected in the Suite launch configuration), I get the following error
"The input element of the launch configuration does not exist"

If I select the Junit 4 runner it runs, but of course none of my JUnit 5 Jupiter tests are included in the suite.
