OpenBve not starting, forever loading

Hi, I have a bizarre issue after many years of successfully running OpenBve.

I have a fresh install of Ubuntu 24.04 and I installed OpenBve from the official deb file (version 1.10.0.1).
It launches fine but whenever I choose a route/train combo it stops on this screen at 0%
where it says it is loading the route.

Strangely enough the log shows that the route has been loaded and so the train.

This was a route/train that always worked ... and if on the same machine I launch an "uninstalled" version on OpenBve 1.5 it loads fine.

This happens with every route/train combo but if use the Animated Object Demonstration Route available in the extra then it partially loads:

Here it stops and hangs at 54%

Anyone can point me in any direction (I tried downgrading to 1.10.0.0 and 1.9 but no luck)?

On the command line there are no errors or warnings.

Thanks

Is this an AMD graphics card by any chance?

If it is, the official drivers seem to trigger this randomly on some systems.
I've not got one, so I can't be more specific than that.
