First of all, that loading time of 2 minutes is not normal. That indicated some kind of problem, because even in the worst case, FP should not take more than a couple of seconds to initialize.
There is nothing we can optimize or improve using multithreading. You see one CPU at 100% just because Max is freezed at some specific process.
In this case, checking your minidump, we see Max is stucked trying to load the Forest templates.
These are a set or simple geometries used for billboards. Usually are stored at C:\Program Files\Itoo Software\Forest Pack Pro\geometry\objects\geometry1.max.
Under normal conditions, this step should be immediate. Something is interfering with the load process.
Since this issue also happens with other users of your team, there must be something in common, which is causing it.
- In your organization, Forest is installed by default, or do you use some custom configuration ? (i.e. Forest files moved to a network folder)
- What other plugins or scripts do you use ? We have seen cases of custom scripts causing undesired side effects.
I would suggest you try reinstalling Forest with the default settings, and also remove temporary other plugins or scripts, to see if there is some difference.
