[radu-v]

Getting a plugin error notification in Rider (2022.1) with a missing class exception.
Noticed in plugin versions 1.11-1.12.

com.intellij.diagnostic.PluginException: com.jetbrains.rider.plugins.specflowriderplugin.SpecflowLanguageSubstitutor PluginClassLoader(plugin=PluginDescriptor(name=SpecFlow for Rider, id=com.settler.rider.specflow, descriptorPath=plugin.xml, path=~\AppData\Roaming\JetBrains\Rider2022.1\plugins\specflowriderplugin, version=1.11, package=null, isBundled=false), packagePrefix=null, instanceId=14, state=active)
