Slice failed with multiple projects that works on 5.3.1. Attached the simplest one.

I checked logs and found in cura.log:

2024-01-26 22:20:14,909 - DEBUG - [EngineOutputThread] UM.Backend.Backend._backendLog [140]: [Backend] [2024-01-26 22:20:14.908] [info] Using plugin: '-' running at [127.0.0.1:58669] for slot 200
2024-01-26 22:20:14,910 - DEBUG - [EngineErrorThread] UM.Backend.Backend._backendLog [140]: [Backend] terminate called after throwing an instance of 'cura::plugins::exceptions::RemoteException'

So, it looks like backend is crashing.
Few lines earlier I found reference to CuraEngineTiledInfill.log:

2024-01-26 22:20:13,998 - INFO - [MainThread] cura.BackendPlugin.start [77]: Starting backend_plugin [CuraEngineTiledInfill] with command: ['/home/xxx/.local/share/cura/5.7-alpha/plugins/CuraEngineTiledInfill/CuraEngineTiledInfill/x86_64/Linux/curaengine_plugin_infill_generate', '--tiles_path', '/home/xxx/.local/share/cura/5.7-alpha/plugins/CuraEngineTiledInfill/CuraEngineTiledInfill/tiles', '--address', '127.0.0.1', '--port', '58669']

I checked CuraEngineTiledInfill.log and found:

So it looks like it doesn't like my old system.

I disabled 'Cura Engine Tiled Infill' plugin and slice works again.

It looks like this bug: Ultimaker/CuraEngine_plugin_infill_generate#7

[imtippmann]

Please add the Hilbert Curve Infill pattern to Cura. This popular infill is proven to produce 3D printed products that are efficient thermal insulators and it is needed for many other applications.

[fieldOfView]

@imtippmann, please create a new issue for that request, since your request will almost certainly go unnoticed in this mostly unrelated thread.

Hi, @imtippmann , see https://github.com/smartavionics/Cura/releases for a Cura variant that provides the Hilbert curve infill pattern (also for skins).
