When trying to expand, view, or create Custom Views in Event Viewer, you may receive the error, "MMC has detected an error in a snap-in and will unload it." and the app may stop responding or close.

Internet Explorer 11 may stop working when loading or interacting with Power BI reports that have line charts with markers. This issue may also occur when viewing other content that contains Scalable Vector Graphics (SVG) markers.

Markers can be turned off by selecting the line chart that is having issues and going to the Visualizations pane. Then on the Format tab under Shapes, set the Show marker slider to off.

Next steps: We are working on a resolution and estimate a solution will be available in late June.
