NVDA freezes in IntelliJ

Henk Mulder


Using NVDA 2019.2.1, NVDA randomly freezes when I open IntelliJ IDE (Community edition 2019.2.4).
When it happens, NVDA hangs and won't report anything (also when switching to other applications with alt+tab). Also IntelliJ hangs and will not open the current project. The only thing I can do is to start Windows Narrator, which does keep working, and end the IntelliJ process via the task manager. When the IntelliJ process is killed NVDA unfreezes.

Is there a way to make sure, or to increase the chance, that I can start IntelliJ without NVDA and IntelliJ locking each other?

When NVDA is back I have the following snippet in the log viewer:
