IntelliJ IDEA 2022.1 EAP complaining

[ThexXTURBOXx]

Every once in a while (haven't figured out what causes this exactly. However, it seems to have to do with switching projects and opening IntelliJ), IntelliJ shows this error:

com.intellij.diagnostic.PluginException: Do not use toolWindow.setAvailable() as part of ToolWindowFactory.init().
