SourceTree crashes shortly after launching application.

We currently can't use the SourceTree windows application on any workstation issued by our company. The application installs but then simply closes a couple of seconds after it is launched. The behavior is identical on three workstations where SourceTree was evaluated.

Windows and hardware specifics: 11th Gen Intel(R) Core(TM) i7-11850H, 16.0 GB ram, Windows 10 Pro, 21H1,OS build 19043.2251, 120.2212.4180.0

During installation (defaults selected throughout) the following error occurs:

After clicking 'cancel', the installer appears to download Mercurial again, with the second attempt being successful (apparently).

After installation completes and attempting to launch Sourcetree it crashes, sourcetree.log has the following records:

We have tried several older versions, including v3.0.17 and v2.6.10, which have the same issue of closing/crashing a couple of seconds after the launch.

Could you please provide a workaround/fix? Thanks.
