Kdenlive 23.04.2 crash

Trying to edit a video with a bunch of clips on Windows 10 and now on my Gentoo PC.
Not sure where to dig in Windows, but Linux says below:

cat /var/log/messages|grep kdenlive
Jul 17 17:04:16 calculate kernel: kdenlive[3917]: segfault at 108 ip 00007faeb6eb9d1d sp 00

ate #1

I got a few 2000% speed clips in the project if it makes any difference.

Does it render properly when taking the sped up clips out?

Yes, it renders well. I’m not really sure how to narrow it down to the sequence I have here to reproduce it. The thing is that I can’t downgrade to the previous version because it fails to understand the project file from newer version. From the other hand, I don’t want to start editing from scratch.
Some additional details: I use proxy files as original files are VBR. I used to do trans coding to CBR in the past but it doesn’t make any sense and just increasing a lot of working time and triple space needed for the source files.

Well, now that we know what causes the crash we need to fix that. VBR is an issue so I recommend to trans code at least those clips that have VBR and are sped up.
