At first, please make a zip of your project as backup.


I think that somethiing is wrong in some file in the <projectdir>/.cache folder.

  1. You want to stop Katalon Studio.
  2. You want to delete <projectDir>/.cache directory somehow. On mac, use Finder. On Windows, use Explorer. Or you may want to " rm -rf .cache" in the commandline.
  3. Then restart Katalon Studio, reopen the project.

Do you use git? In the .gitignore file, are you ignoring the .cache/ directory? If not, you should ignore it.


In the backup zip, do you find any file in the .cache directory containing any <<<<<< String? To me, this character sequence seems to be the marker of Merge conflicts inserted by Git.

Hi @lefak.fakiy,

Please share the Customs keyword folder with us

Initially I renamed the Keyword file and was able to continue working. But this morning, the issue came up again. I have followed your suggestions and was able to successfully get back into Katalon.

This issue has only happened since the upgrade. I wonder what has changed.

we are not ignoring .cache/ in our gitignore file. I’ll be adding that to see if there are any improvements in our load time (which has progressively gotten slower as our project grows).

Please find file attached.
