Hi wills,We have checked your sample and the arrays you are
populating for the grid dataSource, and the columns are not destroyed properly.
So, we suggest using the below solution and reference links to overcome the
reported issue.

override ngOnDestroy() {
      this.dataSource.length = 0;
     
  this.columns.length = 0;
    }
