I see something similar ... maybe same or different issue.

I installed a clean portable version of MM5, and did not check the option to start MM5 from the installer.

When i then started MM5 manually, I got [url=https://www.dropbox.com/s/cf5aq03zkb7hty5/MM5%20crash%20on%20start.png?dl=0]this error[/url], and needed to kill of MM5 with the Task manager. ... this time complaining about CodecPackVersion, not waveform
It ran OK when i started MM5 a second time.

I'm getting exact same error with a clean portable install. After about 3rd restart it seems to be working OK now.

Mine works after the first failure. It was a full install over the last version(s).

You might want to capture this in a debug log (step 4b) and attach it to a Support Ticket: https://www.mediamonkey.com/forum/viewtopic.php?f=30&t=86643

Did you do a Portable or regular install and did you install on top of a previous install or do a clean install?

Same here. This build is totally broken for me and won't start. Need to kill with Task Manager. I've sent the logs. Error was something like "Cannot read property 'waveform' of undefined.

Just loaded new version of MM5 and 'Start Media Monkey'. It came up and I pressed the play button. Shortly after (10-15 sec) I got an error and sent the log. ID was A45044E8. It then locked up and I had to taskmanager to end it
