Rendering with VST3 on audio crashes 100% of the time.

Trying to render out some clips with a looming deadline... all my tracks have VST3 applied and Premiere crashes 100% of the time when i include audio in the render. I've just tested by starting a fresh project, adding a clip, applying a vst3 and then exporting. Pr 14.4 cannot render audio + vst3. Even Render and Replace fails and crashes the app.

This is a disaster.

i've tried just about everything at this point, and the only thing that works is Exporting without the audio track. Nesting doesn't work, render and replace, new project, sending to Media Encoder, everything. It's all crashing. I have no problem using these plugins in my audio apps.

have you checked with the company that makes the vst3?  Is it supposed to be compatible with premiere?   Will it work with audition?  If so, you might be able to send your sequence to audition or any of many DAWs...  When you say render, do you mean export?  Or are you rendering the timeline within premiere?  Were you ever able to hear the effect of the plugin?   Did this work in an earlier version of premiere?  If so, you probably should revert to that version...

thanks for the questions. I tried any and all vst3 and they all crash the app when either rendering the audio or exporting the sequence. For many vst3, i also have identical vst2's and when i deleted all the vst3 from my tracks and subbed in the vst2 equivalent, the crashing stopped. Within Premiere, the vst3 plugins were working fine and as expected. Only when trying to render/export would the app crash. 

All the clips i needed to export were built over the past week in this version of Pr, so i wasn't able to use an earlier version. I'll see if i can get someone's attention on feedback to file a proper bug report.

i work for a plugin company and we've also received complaints from our customers that the VST3 version of our plug-in is crashing Premiere after an export is completed. just confirmed this in Premiere Pro 2021 (version 15.1.0 / build 48).

 

after some investigation it looks like the crash is caused by Premiere calling the constructor of both the plug-in's processor and editor when starting to export, but only calling the processor's desctructor after the export is finished, leaving the editor hanging (while probably also leaking memory?). our plug-in works in every other major host so it definitely seems like Premiere is doing something wrong here.
