Model creation & analysis extended delays

Summary:

When running a model analysis, I've noticed that the process consistently gets stuck at 38% for an extended period of time. It doesn't fail or throw an error—it just sits there without progressing. Has anyone else experienced this issue?

The delay occurs when running a model that includes multiple controls and data sources or two to three data points. No recent changes were made to the model configuration. I've tried restarting the analysis, but it always halts at the same point.

Is this a known issue or limitation?

Could it be related to data volume, performance settings, or background jobs?
