Mainstage 3 no longer starts - crashes on startup

Folks, HELP please

I haven't used Mainstage for about 1-2 months so I can't say exactly when did it break. I thought it was the upgrade to Mojave, but according to Apple the latest version IS compatible, so I have no idea what's going on. Essentially, when I try to open it, Mainstage immediately crashes with the error message below. I read several articles with tips, like uninstalling and reinstalling, etc. So far, nothing works. Any ideas? Thanks in advance.

Folks... Problem solved!

YES, the culprit was Cylance Protect. Thanks A LOT @astiocle for pointing that out.

Cylance first blocked the library for MainStage and then blocked the same library for GarageBand.

I have no idea how Cylance decides to quarantine the files - it's definitely when I open the app.

Anyway, after un-quarantining the files, everything is back to normal.

Ok, I just figured mine out. As I was looking up the error, I came across an identical error that someone had with Logic X Pro (Logic Pro X Crash Fix MAResourcesPlugInsS… - Apple Community). This was due to Cylance (antivirus) quarantining the files thinking they were malicious. I have Cylance running on my computer and low and behold, the files had been quarantined. I released them and reinstalled one last time and MainStage is back up and running for me.

Give your antivirus logs a look and see whether the files are being messed with. Specifically from your error above: /Applications/MainStage 3.app/Contents/Frameworks/MAResourcesPlugInsShared.framework/Versions/A/MAResourcesPlugInsShared. This is one of the files within the application package which is how I filled out the full path. Hope this works for you too!

Have you tried trashing the preferences plist, emptying your trash and then starting MainStage again?

Do you live anywhere near an Apple Store so that you can go and show a Genius what is happening?
