@Vinh Nguyen Give me an idea how to send it. I tried message, but it says file is too big (even zipped) ---

Your whole project files are broken. Do you resolve your conflicts automatically when you pull your project? There are some unusual git merging lines so that’s why Katalon Studio can’t parse it. ---

I pulled first part of the project and then I didn’t pull or commit anything. I created bunch of test cases. Everything worked. I was able to exit Katalon and then reopen the project… Than this issue happened without any additional related steps… I need at least to understand how to avoid such situation in the future…I want to present this tool… ---

This issue is reproducible again in another project. I do not use GIT for it… The bad thing is I don’t know, how to recover it now… ---
