Logic Pro X crashes opening particular project (.logicx) file

I have one project I worked on yesterday that crashes Logic immediately every time I try to open it. I've attached the crashlog.

Logic Pro 10.6.1 crash

In the past when this has happened, I've generally been able to use the Import function (in the Browser > All Files) to pull in most—if not all—of my tracks/content, but this time it also crashes immediately on either Open or Import (in the Browser).

It's the same situation with my Backup copy of the project. This a very bad and very frustrating situation as I've now lost a bunch of work. If there are any long-time/power users out there who know any tricks—e.g., things that can be deleted from the logicx bundle(??)—any help would be very much appreciated.

MacBook Pro 16″, macOS 10.15

Is it possible to load the project with core audio disabled?

If yes, you can track down the issues to audio drivers, plugins, dongles or other audio related elements.

"(...) things that can be deleted from the logicx bundle(??) (...)"

I am not sure what you mean by that, but I usually manage logic projects as a folder, never as a package.

Thanks for the link yoyoBen. I have tried most of those things, but not all. Like many of the plugins I use, my UAD Apollo x8 driver is not certified for Apple ARM, and I have no idea why Celemony Melodyne 5 switched in that troubled song to ARA mode all by itself (and ARA mode doesn't work in Logic). In other words, the finger-pointing would be endless, because very few things are truly supported. I just keep submitting crash reports, and there really aren't that many.

In this particular instance, I tracked the problem down to Logic's own Bass Amp. Enabling it would crash Logic in an instant. I'm not the one to troubleshoot why, or even if it would crash in another song. I don't rely on it.

The good news is that I was able to start working on that song again, so all is good. I still can't believe the amazing job that Rosetta2 and ARM/m1 are doing. I've actually switched from my dedicated studio computer to a MB Pro 13 - it's that good.

Unfortunately it doesn't work with Core Audio disabled either. The crash is really instantaneous; it doesn't seem to even start loading plugins, and there don't appear to be any plugin errors indicated in the crashlog (though I admit I'm not great at reading those).

The .logicx "file" is just a bundle (a folder), with data in it. I've seen at least one case (on a Logic forum) where somebody was able to rescue a project by replacing the "ProjectData" file with a backup from .logicx/Alternatives/000/Project File Backups/07. I tried the last couple of those in my file, but no luck. There are also .plist files in the bundle (basically, preference files) that I'd wondered about—i.e., whether those could become corrupted somehow (this is certainly true of ~/Library preference files).

Same problem here. Running on the ARM chip. Fortunately it's only one song. Unfortunately, it's a song with a lot of tracks and plugins, so troubleshooting is a pain.
