Hi,

Suddenly, after not being able to export a sequence, Avid MC stopped working properly.

After booting the application, when I open a project I get the following error message:

assersion failed: m_valid File:/Builds/workspace/MC/Release_installer_Git/Mac_Build/coresw/VolumeUI/volMenuUtils.c Line: 1089

then I can choose from debugger, continue, exit applictaion or create report, but I can't work. if I choose continue, I'll get this message on everything I try to do.

It happens in all my projects, including a newly creatd one.

I tried the following:
Restart the computer

uninstall and install Avid MC again

Deleting the latest render files, thought maybe they caused the problem.

but the problem persists. Please help! I can't work!

iMac Pro 2017

OSX Mojave 10.14.6

Avid MC 2020.5

Okay, after many more trials, I found out that if I remove one of the Raids I'm working with, the problen's gone. But what if I need to work on footage on that Raid?

Hello,

Have you tried to delete the pmr and mdb database on this raid volume?

This will cause the Media Composer to rescan your volume and recreate new, and hopefully uncorrupted metadata. You have to do this in each folders within the MXF folder.

Regards,

Benoît.

I tried it, ant it worked.Thanks.

I'm still having the problem if I attach a hard drive while Avid MC in on, even if that drive doesn't hane an Avid MediaFiles folder in it.
