Unable to run Spring boot project

Hi, 

I am trying to run a spring boot project in Intellij. The project was running fine until I updated my Git branch. Ever since then, the project has stopped executing entirely. Whenever I click on Run or Debug, the run/ debug button grays out and nothing happens. I have tried everything, from re-installing Intellij to downloading a fresh copy of my project, but still I am facing the same issue. Other spring boot projects run fine in my intellij just that this particular project has stopped running. I tried to run the same project on another machine (same specs) with Intellij and it runs fine. Please let me know what can be done to fix this issue.
