RiderにRainglow Color Schemesを入れたらRiderが起動しなくなった

未解決だけど、とりあえず記事にしておく。

環境
Windows10
Jetbrains Rider 2018.2

Jetbrains Riderでよさげなカラースキームないかなあと思って探していて、Rainbow Color Schemesというプラグインを見つけてインストールしたらRiderがエラーを吐いて動かなくなった。

plugins.jetbrains.com

ここに

Compatible with: (... 中略 ...) Rider （... 以下略 ...）

(訳:このRainglow Color SchemesっていうプラグインはRiderでも行けるよ！)

ってかいてあるのに、再起動したら以下のエラーを吐いてRiderが起動できなくなった...。
