Scaler3 crashes immediately upon launch. 2025 MacBook Pro, M4 Pro chip, 24 GB, Tahoe 26.1.

I deleted the settings file, deleted app and did a clean install but the same thing happens when I launch. The screen displays for an instant and then crashes and I get the report error popup.

Using in stand alone mode, not in a DAW.

Hi @Sanderson Welcome to the community.  
Does the plugin version work ok?  
Do you have a crash report you could send us please?

Yes it seems to work as expected as a plugin in Logic Pro.

I just started Scaler 3 in stand alone mode while Logic was active (and had Scaler 3 open as a plugin) and it worked fine.

So as a test I closed all apps and rebooted, then tried to launch stand alone first and it crashed as before. I restarted Logic with plugin active and verified it worked. Tried to launch stand alone version again and it crashed as before. Not sure why it worked previously as I described.

Hope this info helps.
