When using youlean loudness meter 2 version 2.4.3 real time in Audacity in version 3.7.2 and apply effect , audacity ends, you can restart and recovers. Version 3.7.1 will work. I haven’t tested other Windows PCs. I am running windows 11 home Version 10.0.26100 Build 26100 which should be the latest version for 4/8/2025. tried many different troubleshooting steps . When i go on my other devices i will check and update this topic

YouLean works for me in Audacity 2.3.2 , but not in 3.3.2 & 3.7.0.  
In Audacity3 the YouLean GUI window appears momentarily, then turns black.  
(This issue may be specific to me).

I think mine was triggered by a windows update since it was running fine for a while and then one day the bug occurred leading me to believe that version had a problem with a windows update. I backed up to 3.7.1 and it works
