Access from event dispatch thread is not allowed

[denis-colliot]

Description

The following error occurs when using the plugin on single or multiple files.

I ran into this error myself; CheckinEnvironment.commit can no longer be invoked from EDT (Event Dispatch Thread).
Couldn't find a workaround to continue committing files with AbstractVcs... 🤷‍♂️

You could try switching to com.intellij.openapi.vcs.AbstractVcsHelper to commit file(s)?
