Update from 3.4.9 beta to 3.4.10 beta fails

Dear support,

Having version 3.4.9-beta-1.
Got a notification to update to 3.4.10-beta-1
When I click update, it fails with the following:

Method not found: 'Void SharpCompress.Readers.IReaderExtensions.WriteEntryToFile(SharpCompress.Readers.IReader, System.String, SharpCompress.Readers.ExtractionOptions)'.

Then I cannot open Sourcetree normally anymore (with the start menu):
The following exe is not working anymore:
C:\Users\<user>\AppData\Local\SourceTreebeta\SourceTree.exe

I found a workaround: I have to go to the 3.4.9 folder to run it:
C:\Users\<username>\AppData\Local\SourceTreebetaapp-3.4.9-beta-1\SourceTree.exe

The 3.4.10 folder is empty...

Best,
hegyre
