I am using SourceTree Enterprise 22.214.171.124 on Windows 10.
After a Windows Update Today it does not start anymore.
Only see splash screen then it closes.
Tried uninstalling Reinstalling, nothing helped.
In the SourceTree.log I see this error:
ERROR [2023-06-14 09:23:59,047]  [Sourcetree.Composition.VSMef.Net48.VSMefCompositionManager] [Log] - Unable to load MEF components
System.InvalidOperationException: Die Sequenz enthält keine Elemente.
bei System.Linq.Enumerable.First[TSource](IEnumerable`1 source)
bei Microsoft.VisualStudio.Composition.PartDiscovery.GetElementTypeFromMany(Type type)
bei Microsoft.VisualStudio.Composition.RuntimeExportProviderFactory.RuntimeExportProvider.GetValueForImportSite(RuntimePartLifecycleTracker importingPartTracker, RuntimeImport import)
Can anyone help?
Seems that this issue reappears and the above fix has to be applied repeatetly
So i downgraded to 3.4.12 and the issue is gone
Seems to be some deeper issue with the 3.4.13 version
Worked for me after this weeks regular windows update that I declined but somehow it was applied regardless. For what its worth these are the folders in which I needed to delete those files:
"Unable to load MEF components" is not a bug, it's a feature! This happens so frequently it's disturbing why developers do not fix this or auto-remediate for this issue. Incredibly frustrating when this happens.
EDIT: Got tired of this issue happening so often, even on latest version at time of writing, so I stopped using Atlassian SourceTree altogether and started using something else.
