We have had multiple reports of a problem in which the 2nd time that you open Studio One 4, the plug-in scan window will lock up. This is only happening on Windows 7 with some NVidia graphics cards. We have seen this issue mostly with 4k monitors as well as ultra-wide monitors. Below you will find troubleshooting steps that we have identified will resolve the issue.
This issue is when you try to launch Studio One 4 a second time, the program goes into a state of "not responding" when it is loading plug-ins. It is important not to confuse this issue with plug-ins being blocked by antivirus software or with plug-ins causing a crash in Studio One.
If you are running into this issue, you will need to update to Studio One 4.1.1 or higher. This update will resolve the issue.
