Relationships between tables and PowerBI crash SQLDUMPER.exe

Hello everyone, 


Since the new December version has been released, I keep having crashes of Power BI over and over trying to link two tables... 


As soon as I want to create the link (drag and dropping a dimiension to a table to another table) the windows terminal opens with SQLDUMPER.exe and close/crash Power BI.


I have never experienced this before the last release.


Thank you for your help

Same issue here. Trying to create a relationship between two text columns. One table is very small, the other is ~400k rows.

Ditto. Same problem here with two tables that are ~10K and ~100K rows, respectively.

Same issue for me with december version. Refreshing tables more than 200 000 lines, SQLdump black window appearing and quickly disapearing then getting this message on the request window : powerbi desktop failed to save modifications to the server. Rolling back to november version is refreshing fine with exactly the same .pbix file. See error message in French below. This bug is very impacting. Hope you will  correct it in January.

I also observed this. But as per my analysis when a new relationship is created between two tables and relationship turns out to be many to many then SQLDumper.exe opens up and PowerBI crashes.


Team, can you look into this.
