Steps to Reproduce

Instal the EAP version of IntelliJ, use the IDE for a while. This pops up.

Versions

• The first two lines of the Help -> About output:

IntelliJ IDEA 2021.1 EAP (Ultimate Edition)
Build #IU-211.4961.33, built on January 28, 2021

• The version of intellij-emberjs (Settings -> Plugins -> Ember.js):

2016.2.4-0

[Turbo87]

2016.2.4-0 is a very old version, that does not support IntelliJ 2021.1. Support for this IntelliJ version is still work-in-progress here.
