Presto crashes Visual Studio 2017

Let me start with saying thank you, the tool is great, helps a lot!

Recently I started experiencing an issue whereby Visual Studio 2017 crashes, and upon restart it claims that the crash was caused by the Presto Coverage 1.16.6 extension. The crash happens after running a coverlet command to update coverage info in c:\coverlet and (presumably) Presto picking up the changes.

Any ideas on how to resolve this? Visual Studio is 2017 v15.9.15 and 15.9.16

Steps to reproduce: Environment: I have two instances of VS 2017 running (A and B), with two different solutions open. Both have coverage reporting using Coverlet and Presto. Coverlet saves coverage info to c:\coverlet in bot solutions. Coverage json file names include project names, so no collision there.

• "A" has a solution with stale coverage info (unit tests have not been executed for some time).
• I execute unit tests in "B"
• I run coverlet for solution "B" (updating coverage info in the shared location)
• VS "A" crashes, stating that Presto extension is responsible, asking whether I want to disable it. If I execute unit tests in solution "A" (in VS Test Explorer) take the same steps as above, VS doesn't crash.
