Does this error still happen now? It usually occurs when your computer doesn't have enough memory space for Power BI to run. Close other unnecessary running applications/softwares will spare more memory for Power BI if this error just appear occasionally.

Also, if your table is in Import mode and you import a large amount of data into the model, it will consume much memory. You can use a small sample data when creating a report in Power BI Desktop. Then use query parameter to switch data source dynamically. After you complete the report and publish it to the service, you can change the query parameter to use the actual data source which has large data. See reference: Change the Source of Power BI Datasets Dynamically Using Power Query Parameters - RADACAD
