Sourcetree erroneously closing pageant on exit

I have pageant running continuously at startup (i.e. when I log in to my windows account on my machine). When I open sourcetree, and then close it again, sourcetree is erroneously closing pageant. If sourcetree is not configured to open pageant (at the time of starting sourcetree), it should also not then close pageant on exit.

[Note: I have only experienced this issue since approximately 15 March 2021, following a windows update.]
