As per title.
All working fine, until out of nowhere, they all cause fatal crashes in Cubase, or "VST3 cannot be found"/fatal crash in Ableton.
The standalones also just open a red X with no error message.
I have checked and triple checked all VST locations and they are as normal. I have reinstalled them all. I have updated Windows.
Running Battery 4 and Reaktor 6 as administrator seemed to fix the standalone issue. I still cannot open Massive X plugin though.
Cubase throws up a system32/kernelbase.dll error message, and also adds these plugins to the blocklist when reopening Cubase.
All my other VSTS (EW, Arturia, Korg etc) all still work fine.
I cannot open any projects that are using any of these NI plugins, so am looking to get this resolved asap as I have some important projects using them. Thanks in advance.
