I just installed Audacity Version 2.3.0, but I’ve run into some issues using external plugins.
If you go into preferences , select Effects and change Sort or Group from its original setting “Sorted by Effect Name” to “Grouped by Type” the program will become unresponsive, and eventually a bunch of pop-up boxes will display (not at the same time, but after one is acknowledged another will pop up).
"Attempting to initialize the following effect failed: MTremolo. More information may be available here → show log.
Mtremolo is just an example. Audacity will also complain about a handful other plugins.
When the pop-up boxes eventually disappear the affected effects will be visible under “Effect → Unknown” and they can not be used. But if the setting Sort or Group is left with its original setting, - they can be used.
When audacity is exited it will not start again - Unless audacity.cfg which is located under %appdada% → Roaming → Audacity, is modified or deleted
Other: I’m using Windows 10 Home, version 1803
