This appears to be related to an existing JCEF (Java Chromium Embedded Framework) NullPointerException issue in JetBrains IDEs. Related issues:

• Continue is not working (NPE since IntelliJ update to 2025.2 #7285 - Same NullPointerException: Cannot read field "isNull" because "robj" is null in RemoteMessageRouterImpl.create
• com.intellij.diagnostic.PluginException: Cannot init toolwindow #6448 - Same JCEF error (Cannot read field "objId" because "robj" is null) when initializing ContinueBrowser
• [JetBrains] Sidebar panel frequently freezes across all OS' #8085 - Similar JCEF-related crash causing IntelliJ to freeze
• Continue Plugin doesn't works on PyCharm #9105 - Related JCEF browser initialization issue
• JetBrains Plugins use #9159 - Similar unresponsive Continue panel issue in IntelliJ

A fix that may help with this was merged in #11899 — it chunks large JCEF messages to avoid overwhelming the browser bridge. This will be included in 1.0.65.

These issues have been difficult to verify across different environments. If you're still experiencing this after updating to 1.0.65, it would be helpful to know. Thanks.
