voicemeeter freezes all videos

May be something else going on.

Start by reinstalling voicemeeter. Your current installation may be corrupted or buggy.

Then, if the problem continues, use Task Manager to identify the cause of the freezes.

Open Task Manager, observe your system. Leave the window open but slide to one side.

Then run the videos and/or voicemeeter as you normally do. Watch Task Manager for any application, resource, or service that grabs a large % of some resource and causes the freeze.

For example the freeze may prove to be a lack of memory or drive space.
