A low-level exception occurred in: Importer MXF...

[Jim Curtis]

I get hundreds of insances of this Event in the Event tab whenever I try to edit in Pr 2021 15.4, and it was happening in 15.2.

And, I've gotten several Kernel Panics when clicking on the Timeline, or clicking a Project item.

Pr 2021 looks like garbage to me - useless, except for making captions.  What's going on?  I can work with Pr 2020 14.9 with hardly any issues.

Sorry about that, Jim. What is the source footage? Is it from Sony XDCAM or something like that? That's the first thing I'd want to know. Hope we can help.

Thanks,
Kevin

Hi Kevin,  I've been trying to post this answer for hours, but keep getting a bogus error message about "post flooding."

I had tried two different Pr 15.2 projects with Sony .MXF and a Sony FS9 .MXF sources from different shooters.

Just this morning, I updated Pr to 15.4, loaded a project with Canon .MXF, and that's when I got the Event errors and kernel panic, almost immediately.

I was able to do captions on two 15.2 projects by importing an H264 / MP4 exported from Pr 14.x.  The ability to Save an SRT from the Captions Tab was still broken (Save button grayed out), but I was able to make them with the old-school Export Movie / Captions function.

So, you may be onto something associating the issue with certain footage types, namely .MXF.

BTW, I know the drill with Pr, and I've done the troubleshooting routine: delete prefs, reinstall apps multiple times, reinstall OS, trash cache, previews, etc.

Thanks for your interest.
