86Box Manager does not save any new profile created

[Fenix770]

Describe the bug When I create a new profile, 86box Manager does not save the configuration. 86box Dev version 3.0.0.3249 works fine. I suspect this bug appeared on 3.0.0.3250 or later commits of 86box.

To Reproduce Steps to reproduce the behavior:

1. Simply try to create a new profile with the last commit of 86box Dev.
2. Check to see that the config is not saved.

Desktop (please complete the following information):

• OS: Windows 10 21H1
• 86Box version: 3.0.0.3249
• Build type: Dev

PD: I can modify and save any configuration if the template already exist but not a new one.

Transferred the issue to 86BoxManager, because it's the Manager that has seemingly become incompatible with later 86Box builds.

I can't reproduce this problem with Manager 1.7.2 and 86Box dev build 3255, so I'm gonna need more info.

• Does it work fine if you try launching 86Box manually with the -P argument and the config path?
• Have you tried the regular build?
• Can you post the full path to where the config is supposed to be saved?
• Have you tried saving the config to any other folder?

I also have to clarify (again) that 86Box Manager does not save anything or interact with the config in any way. It simply launches 86Box.exe with the -P argument and the path to the config. Everything that happens after that is on the emulator side.
