I finally fixed my Waves causing X3 to crash by doing the following.
Downloaded the latest installer from Waves.
Went to VST settings under Preferences and removed all folders to scan except for C:\Program Files\Cakewalk\Vstplugins and C:\Program Files\Common Files\VST3. I then reset the plugins and then rescanned them. For some reason when I tried to reset the plugins I kept getting a message that a scan was in progress even though it wasn't. After rebooting the computer I was able to reset the plugins and scan again. I haven't had a crash since.
