Thanks for answers. I want to make some clarifications. I personally can’t understand why this error only occurs when I first start the application (after installation). When the application closes due to an error, all subsequent launches are perfect.
But at the first start after installation, the length of the list with questions is 4, but the length of the list with audio recordings is 0. Although both blocks are identical. Why, if the blocks are the same, then the results are different? In one case, the list of questions is loaded, and in the other case, the length of the list of mp3 file names is 0 (but only during the first installation of the application).
The CSV files are correct. Questions are displayed correctly, without brackets, no loops, repetitions and duplication. The problem is not in the list with questions, but in the list with the names of mp3 files.
That is, at the first start after installation, the length of the list with questions is 4, the length of the list with audio is 0. After the application is restarted, the length of the list with questions is 4, the length of the list with audio is 4. And after that I can not reproduce the error. To get this error again, I have to uninstall the application and reinstall it.
By the way, the error appears only in the assembled application. When I test the application through the Companion, there is no error.
