I have not tried safe mode, since the same montage will usually open once I restart the program. It doesn’t not open the montage, it crashes the program. Upon reopening the program it will open the montage without crashing most of the time. Sometimes I will have to restart the program a few times. I can not identify any other variables that are changing with it loading correctly vs crashing. Nothing else is running on this computer when I use WL. I tip toe around the program and am very careful to only launch one process at a time, I stop playback when opening a new montage, I stop playback when enabling and loading plugs to a montage. I’ve been using WL for decades as my main DAW (since it was released in '95) and it has been less stable since version 10 was released. Before WL10 it was unquestionably reliable. These days I can not get through a single day of mastering without multiple crashes and errors telling me files are opened when they are not. Restarting the program often is eating up lots of valuable time reloading the montages and is interrupting the flow of my work. I really hope there is a way to get a stable build of this program so I can keep using it. I use other programs on this same computer with the same plugins and experience no issues or crashes so I know it’s possible.
