JUnit Jupiter 5.5.1 depends on JUnit Platform 1.3.2?

Question

I have an impression that JUnit Jupiter 5.5.1 does not like JUnit Platform 1.3.1. If both are specified in gradle dependency, then all JUnit 5 tests would just be ignored. See my previous SO Q&A on this. For example, I think the following combination would NOT work:

testImplementation('org.junit.platform:junit-platform-launcher:1.3.1')
testImplementation('org.junit.jupiter:junit-jupiter-engine:5.5.1')
testImplementation('org.junit.jupiter:junit-jupiter-api:5.5.1')

Instead, I must use the following combination. That is, JUnit Platform Launcher must be 1.5.1 not 1.3.1:

testImplementation('org.junit.platform:junit-platform-launcher:1.5.1')
testImplementation('org.junit.jupiter:junit-jupiter-engine:5.5.1')
testImplementation('org.junit.jupiter:junit-jupiter-api:5.5.1')

That was a few months ago. Today, I just realized that in my project, those JUnit 5 tests are being ignored again. Upon deeper inspection, however, I found the following dependency chain:

+--- org.junit.jupiter:junit-jupiter:5.5.1
|    +--- org.junit.jupiter:junit-jupiter-api:5.5.1 -> 5.3.2
|    |    +--- org.apiguardian:apiguardian-api:1.0.0
|    |    +--- org.opentest4j:opentest4j:1.1.1
|    |    \--- org.junit.platform:junit-platform-commons:1.3.2
|    |         \--- org.apiguardian:apiguardian-api:1.0.0
|    \--- org.junit.jupiter:junit-jupiter-params:5.5.1 -> 5.3.2
|         +--- org.apiguardian:apiguardian-api:1.0.0
|         \--- org.junit.jupiter:junit-jupiter-api:5.3.2 (*)

Does anyone know why here Junit Jupiter 5.5.1 would depend on JUnit Platform Commons 1.3.2

Update with more info from dependencyInsight

Based on the discussion here in SO and in discuss.gradle.org, the -> means there has been a "conflict resolution" of dependency and we could use the task dependencyInsight to gain more insight. I did that but still I could not quite know how to interpret the result.

My ultimate goal is just to get my JUnit 5 tests running. Any ideas on how to do that?

Update 2 -- added gradle files

The gradle build files (and gradle.properties) are listed on this GitHub Gist. This is a multi-project build, so the root directory has build.gradle and one of the sub-project profiler has profiler.gradle
