Odin2 fails to instantiate in Zrythm

[alex-tee]

Transfering this bug from our tracker because it seems to be an issue with Odin2

See also: https://redmine.zrythm.org/issues/2229 and https://todo.sr.ht/~alextee/zrythm-bug/87

Note that I can't reproduce it on my GNU Guix machine because I can't build the plugin - see #375

To Reproduce Steps to reproduce the behavior:

1. Install Odin2 LV2 on your Pc. (https://www.thewavewarden.com/odin2)
2. Add it to Zrythm.
3. Plugin fails to instantiate

Expected behavior not crash

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu 20.04 Virtual Machine (Qemu)
• DAW and version being used: Zrythm (trial) 1.0.0.alpha.5.0.1
• Odin Version: Not sure, likely latest release
• Plugin Format: LV2

Additional context log shows that it crashes inside lilv_instance_activate(). This suggests there's something wrong with the activate() logic of the plugin.
