NullPointerException when adding Run Configuration

[max333]

When trying to add a Haskell Stack REPL (or Run or Test) configuration I get a NullPointerException.

I'm on Ubuntu 20.04, intellij.haskell (1.0.0-beta87) and Intellij 2021.2.1 (Build #IC-212.5080.55, built on August 23, 2021). I reverted to Intellij 2021.2, but it did not help. I'm not sure when this problem appeared since I don't add Run Configurations very often.

java.lang.NullPointerException

The stack trace is much longer, but the rest seems irrelevant.
