Unending Indexing of project in IDEA 2016.3.2

Back to work and I just updated to IntelliJ IDEA 2016.3.2, but the project I was working on before the break I cannot open? The indexing gets to 100% but never ends, so I cannot use most of the editor functions or refactoring? also cannot stop the indexing manually? Seems like the update has bricked my IDE (CentOS).

I've tried quitting IDEA and restating also wiping out all caches and restarting but it behaves the same way after reindexing crawls back up to 100% There's no indication of what if any file it is stuck on if any and the log doesn't have any errors from indexing, just that its rebuilding the index.
