I have recently upgraded to a newer version of Illuminated Cloud and it hasn't been working. Whenever I open a project, a progress bar on the bottom right says 'indexing' and gets to maybe a third of the way. Then, the entire IntelliJ application permanently freezes. In other words, the IDE is completely unusable. Please help!
More details are below.
Illuminated Cloud - Version 126.96.36.199 - Build 20190215084325
IntelliJ version 2017.2.5
