Error 1103 Help me

It is currently showing an error 1103 for a type of launcher that I produce, even after being compiled and signed. The error has been showing since the end of 2023. Even for new projects the error persists. We are unable to access the applications and the banner does not display after the message. I have tried several ways to fix it, but the error persists even after changing devices and internet networks.

error 1103 can indicate that the destination hostname, folder, or file names are invalid. To fix this, you can check for illegal characters in the names and confirm that the names conform to the naming syntax. This can also apply to urls.

The entire code has been reviewed and does not contain any characters with errors. However, on some specific devices the error does not appear, even if it only hides the message, the error continues and prevents access.

Without any further information provided, you will need to debug every file,folder,path and url, until you find the one that is causing the problem.
