Summary0010119: Ardour crashes after loading step "indexing plugins" when opening projects by clicking on the .ardour project files
DescriptionArdour crashes to desktop after loading step "indexing plugins" when opening projects by clicking on the .ardour project files. However, opening Ardour.exe and open projects from the "recent projects" list or browse projects not on the list works, and does not crash on the same step.
Steps To ReproduceOn affected systems: click on any .ardour project file
Additional InformationI reported this in the Ardour forums as well, and another user on MacOS responded they had the same issue there and suggested I open a ticket here, see: https://discourse.ardour.org/t/problems-opening-projects/112791

This phenomenon happened "over night" about a month ago; it was working fine until then and hasn't worked since. I had not done any updates to Ardour at that time, nor recently installed any new plugins, but I did try to reindex/rescan all plugins again anyway, without it solving the issue.

I'm on an AMD Ryzen 7900x CPU with 64GB RAM, working off of SSDs (M.2 for OS/applications, SATA SSD for music projects).

I cannot reproduce this. Works fine on all 3 platforms with Ardour 9.0-rc2.

Also the forum thread you reference is for Mixbus. .ardour sessions were never registered to launch Mixbus in the first place.

I only have a handful of Plugins on Windows, so maybe the issue is somehow related to that?
Sadly I don't know how one could debug that when launching Ardour like this, since interactive debugging is not possible either.

I opened the forum thread under "installation & configuration" for Windows, didn't see anything about Mixbus, but someone "hijacked" the thread with a lot of Mixbus comments later; I always referred to Ardour.

But this might be fixed in Ardour 9.0, then? I'm on 8.12. When's 9.0 planned?

> When's 9.0 planned?

There are no plans, it's ready when it's ready. It is currently in beta-test release candidate state. So it depends how how many bugs are reported and how fast they can be fixed.

PS. You could try a https://nightly.ardour.org/ build (demo is fine and it be installed in parallel to Ardour 8).

That is even more mysterious then.

Does it affect all .ardour sessions? or only some specific ones?

I haven't come across any sessions lately where it didn't happen, so it's certainly affects all of my recent .ardour sessions, which also includes a couple of sessions I hadn't visited for several months.
