Hey guys! I have opened a support ticket regarding this issue.
Line 6 was very helpful sent me a step by step solution to this problem...and it worked perfectly! It seems that I was forgetting one of the steps before. Helix Native is now running on my Macbook air m1 with macOS Monterey! Here it is:
" Below are the files to uninstall. It's crucial to remove the files/folders from the hidden library:
1) /Library/Application Support/Avid/Audio/Plug-Ins/Line 6/Helix Native.aaxplugin
2) /Library/Audio/Plug-Ins/Components/Helix Native.component
3) /Library/Audio/Plug-Ins/VST/Line 6/Helix Native.vst ; /Library/Audio/Plug-Ins/VST3/Line 6/Helix Native.vst3
4) /Library/Application Support/Line 6/Helix Native/ -- this folder contains all the stuff that makes Helix Native work. You'll see data and res folder; just delete the entire Helix Native folder for a clean slate.
5)~/Library/Application Support/Line 6/Helix Native/*
*Note this ~/Library is your user library and is hidden. Hold Command/Shift/and Period to access.
Once completed, download the latest version, reinstall, and reauthorize.
With version 3.15, you shouldn't need to run it in Rosetta mode. "
-> Line 6 Support didn't actually specified, but the steps 1,2,3 and 4 can be accessed straight from Macintosh HD -> Library
In step 5 the files were located at Macintosh HD -> Users -> [user name] -> Library
I am not sure this will be applied to every user, but I would definitely check both files...
I also deauthorized my computer before reinstalling the new version at line 6 website just to make sure.
And please remember to save a backup library.
