Body

Copilot keeps having problems for me on JetBrain's products. Same issues on both Rider and CLion. This is happening for over a week now and it started all of a sudden.

java.lang.NullPointerException: Cannot invoke "com.intellij.openapi.fileTypes.FileType.getDefaultExtension()" because "this.myFileType" is null

It also seems that if I logout and login again the issue kinda fixes itself. Though Copilot will only accept one prompt and then every other prompt I try to send is as if I never sent it.

Same issue since last update, works for one prompt then crashes and says "Copilot is encountering temporary issues: The pending stream has been canceled (caused by: unable to verify the first certificate)"
