The allowed characters are different when NeoLoad runs on Linux and Windows. For example your scenario name works properly on Linux but on Windows the files that contains your scenario name cannot be created.

You can apply the procedure below to recover your test result but you will loose some of summary statistics.

1. Close your NeoLoad project (NeoLoad can still be started)
2. Go to your project test result folder and make a backup
3. Edit the project.zip file.
4. Edit scenario.xml and project.xml files
5. Search for your scenario name on both files and rename it without any special characters
6. Save and update the file inside the project.zip file
7. Remove the "summary.db" file inside your test result folder
8. Run the command: NeoLoadCmd -repairTestResult "<path to your result folder>"

That should re-create a summary.db file

Open your project in NeoLoad and filter it by time to get some summary data (not all of them).
