[severity:It's more difficult to complete my work]
I get recurring crashes of Visual Studio 17.14.13 (roughly once or twice each hour).

I don't have a reliable repro. My workload is dotnet 8 C# development (net8.0-windows target). Currently test driven development switching between running Unit tests (NUnit 4.3.2 with NUnit3TestAdapter 5.0.0) and writing code.

In event viewer I have the following .Net Runtime error after each crash:

Application: devenv.exe

Description: The process was terminated due to an unhandled exception.

I have the same issue, but with both VS 2026 and 2022. It started when or soon after I installed VS 2026. It's intermittent, and happens when I try to debug unit tests, maybe once every 2-8 times I do it. I'm not sure about non-test debugging, as I've only been working on tests recently.

It was happening in VS 2026, so I tried reverting to 2022, but it happened there too, so I'm back on 2026.

I'm using .NET 8, C#. I've had issue happen with both XUnit (pre v3), and TUnit, and OP was NUnit, so it doesn't seem to test framework-specific.

EDIT - When I commented originally I was using 18.1.0. Updated to 18.1.1 and the same thing happens unfortunately

My Event Viewer .NET runtime error is identical to the OP, and my Application Error is:

Not sure if relevant but this is in the ActivityLog.xml file leading up to it (nothing afterwards). The . NET runtime error occurred along with the final logs there at 16:00:07. It didn't occur earlier within the timeframe of those logs.
