Visual Studio 2017 crashing on load solution

Question

My VS 2017 keeps crashing with following error in EventViewer. Any idea why it's crashing?

Answer 1

To work around the issue: Try deleting the .vs folder (which is hidden by default) that resides next to your solution file. This will make VS forget about any IDE settings for that solution, such as files opened or breakpoint locations. If you don't want to lose those, move/rename the directory instead.

To give feedback and help make the product better: Before applying the workaround, try to capture a crash dump for the issue. Then, report it using the Report A Crash feature in VS or by filing an issue on http://connect.microsoft.com/visualstudio.
