it"s strange that last night the team worked overtime and updated a version to the server, and then I suddenly had this problem when I clicked on the update code. I have encountered such a problem once before, but I have forgotten how to solve it. And now all of a sudden it"s happening again. The key point is that I am the only one with this problem, and everyone else can submit the code to update the code normally. I can log in directly to the code repository to download and submit the code, but I can"t operate it with the git desktop tool.
ask God for help on how to solve this problem. Thank you.

added: I can download my code remotely from my colleague"s computer, but I can"t download my code from my own computer all the time, and I still report the same mistake.
