MainStage stuck on «Instalizing JamPack Manager» when launching...

Hello! I've just moved files from my 2012 MacBook Air to MacBook Pro 13" M1, and I can't launch MainStage: it stuck on «Initializing JamPack Manager». Logic Pro X and Garage Band open well. I've already tried reinstalling MainStage. MainStage on my MacBook Air opens well. Please help!

MacBook Pro 13″, macOS 12.2

Updated to OS 13.3.1 and now Final Cut Pro (10.6.5) won't open ? Hello - I just updated my MacBook Pro to OS 13.3.1 and now Final Cut Pro (10.6.5) won't open. It states to open but get's stuck on "Validating Audio Units, Audio Ease: Altiverb 7 (12/86). It doesn't move from there and I can't close it or force quit so I have to press and hold the power button and restart to get FCP to close. I've tried deleting the preferences but that doesn't help. A few times when I try to open FCP it get's hung up validating a different plugin. I don't think the issue has to do with the plugins as they open fine in Logic Pro 10.7.7. Thanks for any help

MBP M1 will not open universal type programs. My MacBook Pro M1 will not open universal type programs downloaded from Adobe, Serif, etc. It is frustrating spending money on program downloads that won't open. I just get the bouncing icon in the dock, until "program is not responding". I am running Ventura 13.0. My most recent disappointment is that Affinity 2 will not open. I have used Macs for 35 years, and this current MBP M1 is making me want to return to a former intel MBP. I am not a tech guru, so a lot of arcane techie talk is not going to help me. Is there a simple solution that escapes me?

Finder does not open files have a M1 Max MacBook Pro 16 inch 2021- running Ventura (13.0). Quite frequently, like several times a day, finder stops being able to open files. I double click on a file and nothing happens. I right click on the file, get "open with" choose a program, nothing. Nothing helps. If I force relaunch Finder, it begins to work again. Works for a while, but if I open a lot of files this way, it eventually fails. Every file can be opened by the appropriate program, either by "file / open" or by dragging and dropping. But double clicking in Finder does nothing. I have no strange 3rd party software installed What is the problem ...... ?

If you have access to it, try with the previous revision of MS (3.5.3). 3.6 has caused many, many problems for many, many people.
