intelliJ "unknown artifact. Not resolved or indexed" for scalatest with scala 2.13.1, sbt 1.3.3

The following combination in IntelliJ gives the "unknown artifact" error.

The following combination don't give an error.

The suggestions from an similiar question here didn't help:

What am I missing?

Minimal project on Github: https://github.com/hcetinkaya/sbt-scalatest-error-demo

My system:

Environment (updated): 

OS: Windows 10.0 (Build 15063) VM on a VMWare 7.1
Scala Plugin: 2019.2.36
IntelliJ IDEA: 2019.2.3 (Ultimate Edition)
Build #IU-192.6817.14, built on September 23, 2019

    Runtime version: 11.0.4+10-b304.69 amd64
    VM: OpenJDK 64-Bit Server VM by Jetbrains

JAVA_HOME: E:\apps\java\jdk-13
SBT_HOME: E:\apps\sbt\sbt-1.3.3\sbt

build.sbt:

scalaVersion := "2.13.1" // "2.12.10" is OK. "2.13.1" gives an "unknown artifact" error
lazy val root = project.in(file("."))
  .settings(
    libraryDependencies ++= Seq(
      "org.scalatest" %% "scalatest" % "3.0.8" % Test
    )
)

build.properties:

sbt.version = 1.3.3

UPDATE:

sbt yields following error log:

UPDATE 2:

The following combination and steps worked for me

steps:

IntelliJ still shows the "unknown artifact" message but sbt compile, test works.

I assume, that a newly installed IntelliJ had Problems to compile the scala2_12 bridge for Cousier.

The commandline recompiled, now I can see scalatest_2.13, which was missing before, in project directory

null\Coursier\cache\v1\https\repo1.maven.org\maven2\org\scalatest\scalatest_2.13

The following combination and steps worked for me

scala 2.13.1
Java OpenJDK 13.0.1 (set IntelliJ sbt options to OpenJDK)
sbt 1.3.3 (set IntelliJ sbt-launch.jar option to sbt 1.3.3 directory)

steps:

create a new sample project in commandline (see https://www.scala-sbt.org/1.x/docs/sbt-by-example.html)
sbt compile, test should work
import this project in IntelliJ

IntelliJ still shows the "unknown artifact" message but sbt compile, test works.
