P: Export large Sequences via simple custom export plugin crashes Lightroom 11.4
This issue was reported to me by multiple LRTimelapse users that use my LRTExport Lightroom Plugin to export their timelapses.
Symptom: Exporting sequences of multiple thousand images via a custom export plugin consistantly makes Lightroom Classic 11.4 (and later prereleases) crash. This happens on Windows and Mac machines.
There is no problem, with shorter sequences of several hundreds of images, as it appears.
I could reproduce the reports from my users on my machine (Windows 10), latest NVidia drivers, etc.
To exclude the chance of any programming errors in my rather complex LRTExport plugin, I coded a very simple, basic custom export plugin. This simple plugin, also crashes when used to export several thousand images, you can use it to reproduce the issue:

The more images I export, the faster and more often the crash happens. With 4000 images for example, often after 10 images Lightroom closes. In some cases it sends a crash report (which I submitted under my info(at)LRTimelapse email address) in some cases it just closes.
Another scenario that I observed a couple of times is that the plugin stops logging and updating the progressbar but the export actually continues in background (filling up the export folder). Then obviously you also can't stop the export via the X button.
I can reproduce these issues in 100% of all cases when exporting several thousand images.
I went back to Lightroom Classic 11.3.1, where everything works fine in the same scenario.
I already spent two days in analyzing this issue and I'm willing to help to provide more information, if I can. It is very important for the timelapse community that this issue gets resolved asap!
