Potential Solution

• Will require further testing to pin the underlying issue

Reproducing the Problem

dotnet test ./QuantConnect.Tests.dll --filter "FullyQualifiedName=QuantConnect.Tests.Report.ReportChartTests.ExposureReportWorksForEverySecurityType" --blame-hang-timeout 120seconds --blame-crash --verbosity detailed
Adding py.gil in the tests stops the issue from reproducing when running the test by itself but still reprocess when running all
dotnet test ./QuantConnect.Tests.dll --blame-hang-timeout 300seconds --blame-crash --filter "TestCategory!=TravisExclude&TestCategory!=ResearchRegressionTests"
