Open the project suite (.pjs file),the pop-up window reports an error

I can suggest several starting points:

1) uninstall/reinstall

2) save/close the project, open a File Explorer and delete the files within your project's Script folder (be sure to copy them to a separate folder if you need them), then attempt to re-launch and hopefully re-import any existing script files you need. If it's a new project and you don't have any existing scripts yet, just delete the entire Script folder.

3) In the event you are using a version control system like Git, you may need to simply remove any hanging 'untracked' items. To clean you local git workspace you can use something like this from cmd:

*** removes all untracked files, packages, configs, artifacts, logs, etc ***
cd C:\<path to your TC project folder>
git clean -d --force
