Both pluginmanager.exe and vstscan.exe show version 22.11.0.111. Do you increment the version number with each release, regardless of whether there have been any changes? Nothing wrong with that if you do (easy for us to verify we're up-to-rev), but it makes it impossible for users to determine if changes have been made.
Should note that whenever a scan hangs or aborts, it is almost always a problem with a particular plugin, not with the plugin manager.
Back on topic: I have experienced crashes here as well, involving CA-2A and Rapture. Each time, the problem could not be reproduced until after a reboot. After rebooting, the problem reappears, but only once. The following exception (stack overrun) occurs if I drag CA-2A into any FX bin. After restarting SONAR, the problem is gone - until the next reboot.
