I’m trying to migrate to split mode, after install my snapshot from the client side, error:

Plugin 'Rainbow Brackets' cannot be loaded because it depends on plugin 'IDEA CORE' which failed to load.

the idea.log

Plugin 'Rainbow Brackets' (izhangzhihao.rainbow.brackets) has dependency on 'IDEA CORE' which cannot be loaded

How to fix the error? I don’t know which module/dependency is the ‘IDEA CORE’

BTW, even with the error, plugin still partially functioned.

You seems have fully broken IDE installation. Take a look at full idea.log

It seems that the IDEA CORE loaded.
