Doesn't crash for me.

It may be worth uninstalling, moving or removing the remaining Construct2 folder from Program Files (move if you wish to keep any non-standards plugins), reboot, then reinstall. It could be an old plugin causing the issue.

It may also be worth checking '%appdata%\Construct2\plugins' and clearing this out.

Thanks the reboot cleared it up.

Closing as not a bug. Note r170 is a beta release, not a stable release, so it's not the "most stable version", problems are to be expected in betas.
