Crashing when opening mocha pro in AE

Suddenly I can’t open Mocha in AE. When I try, Mocha pops up but then I get this message:

“after effects error crash occurred while invoking effect plug-in mocha pro”

No idea why, as nothing in my system has changed. Any ideas why? The CPU, GPU, and memory are not anywhere near their limits.

[after 10 tries, it has opened. Still would like to know how that can be]

CPU - i7 6700K
Board - Z170A M3 Gaming
RAM - G.SKILL TridentZ Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM
OS - Windows 10 Pro
GPU - MSI GeForce GTX 1050]

Can you try turning off GPU tracking in Mocha Preferences and seeing if that helps you? We have seen a driver problem with the latest Nvidia driver we are trying to address.

Tried that. Still having issues.

Very strange, ok, can you send me the project to maryp at borisfx dot com?
