Read access error with new versions of PyCharm and IDEA

[mtkalms]

What I did

Installed latest versions of PyCharm and InelliJ IDEA.

What happened

An error occurs as soon as a project is opened.

java.lang.Throwable: Read access is allowed from inside read-action (or EDT) only (see com.intellij.openapi.application.Application.runReadAction())

JetBrains has completely redesigned the UI for both programs in version 2023.1. Enabling or disabling the new UI feature seems to have no effect on the error message.

When the new UI is enabled, the buttons for Live Coding and Turtle sessions are not visible anymore.

Otherwise the plugin works fine.
