Guitar Rig 7 : An error occured loading the preset

@KME Hi! Don't worry and Thank you! But actually when I open the file with TextEdit on Mac OS, the text it shows me is literally "7º¬A:¡=ò∏T )N†X˘/é˘Kê)é·∏Ωoü?ST ›∆Æ° “*p¿ ÿê kx 4ZáéÖ" with these strange characters. As you can see in this image.

I'm seeing the same problem. As suggested, replacing 'Guitar Rig 4' with 'Guitar Rig 7' in TextEdit seems to work. HOWEVER:

1 There is no way I'm going to do this manually, one by one.

2 I don't trust that it won't cause some future underlying compatibility issue.

3 More importantly, the vast majority of my presets are un-editable like @diego-sala's.

I'm on Ventura. I've tried both "Import Guitar Rig 6 Presets" via Preferences and "Import" (a single preset) via the File menu. Tried in standalone, AU, VST3.
