Zyn resets itself

Nobody has claimed this yet.

### System Information

aarch64 Ubuntu on top of Termux

### LMMS Version(s)

1.3.0-alpha.1.727+g95a051808 (I build from source)

### Most Recent Working Version

_No response_

### Bug Summary

When exporting audio and loading projects, Zyn will reset itself.
On loading it cannot remember presets (and probably anything else).
On exporting, it'll set everything to default then export the music.

I am afraid that it's a "It Doesn't Work Only On My Machine" type of thing, like the Equaliser taking well over a minute to load for the first time.

### Expected Behaviour

Zyn using the presets I told it to use.
I want my strings, dammit :/

### Steps To Reproduce

Load up LMMS, get a preset like the DualStrings Oct2 for example, make it play something and export.

### Please search the issue tracker for existing bug reports before submitting your own.

- [X] I have searched all existing issues and confirmed that this is not a duplicate.

Start by reproducing the issue in Zyn using the DualStrings Oct2 preset, then test both project loading and audio export on the reported aarch64 Ubuntu-on-Termux setup. Check whether presets reset during either operation and use that behavior as the regression criterion; the report provides no source files or tests to inspect.
