Hi debiagui - Export the schema of the old model using Tabular Editor.Import it into a new Semantic Model and reconnect it to the Lakehouse.Open the model in Tabular Editor.Locate the MaxIntermediateRowsetSize and TimeOut properties and increase their values (if allowed by your configuration).

Compare the two models (old and new) using Tabular Editor or Power BI Desktop to identify differences in structure, partitions, and measures.If the old model is corrupted, export and reimport its components into a fresh model:Use Tabular Editor to export the metadata from the old model.
Import the metadata into the new Semantic Model.
