Sourcetree won't open

[Héctor Mar]

Hi all, a user of our company is having trouble to work with Sourcetree.

When she uses Sourcetree for the first time, it opens succesfully and she can work normal. But when she closes it and later on she has to open it again it won't open unless she restart her computer. Her version of sourcetree is 3.4.19.

Have you all have any suggestions to resolve this weird behavior? We have deleted some old cache and such, but the problem persist.

Thanks!
