Ever since upgrading from 550 to 643 Vegas 19 has been crashing intermittently. Doesn't seem to be tied to a specific action, most recent crash was just while building proxies after importing some files to a new project. My system was working without crashes in 550. I'm confident this is a issue introduced in 643 as I reverted back to 550 and been working in new project, with same files, and it's been running fine without crashing for full edit for couple hours now. I couldn't edit for more than minute or two in 643 before it would crash. I did update my video driver when it was released 06/29/22. Vegas 643 was crashing for week before I updated the driver so don't think it's driver related but yeah, I know that's the first thing that gets asked, so yes, I'm running latest graphics driver.
Here's my details. I have six error.zip files, with dump files, happy to upload one. I gave one to support already but that seems like a dead end as they just sent me generic crash troubleshooting.

Intermittent crashing - latest was starting new project adding new files and crashed building proxies during import. It's pretty much random though.
I dumped callstack, looks like AV null pointer in MXVideoAllocator.dll. As much as I can tell without symbols.
