Python DuplicateOptionError on MO2 1.50 start

[nesingho]

The problem:

After update from MO2 1.4.4 starting MO brings up an error message:

Error

failed to initialize plugin ../MO2/plugins/basic_games:
DuplicateOptionError: While reading from '<string>' [line 17]:

To Reproduce:

Update from 1.4.4 or new install in fresh folder.

Environment:

• Mod Organizer Version that exhibits the issue: 1.5.0
• Last Mod Organizer Version that did not exhibit the issue (if applicable): 1.4.4
• Desktop OS/version used to run Mod Organizer: Windows 10 Pro 22H2

Details:

MO2 starts without problems after klicking away this error message. I've searched all files in MO2 relevant folders for the option 'user.throttle.bandwidthkbps' with grepwin but found nothing.

Nothing related but the error message:

This look like a broken settings file for EA Desktop - Maybe try starting EA Desktop, modifying a setting and then saving, and then relaunching MO2, maybe it will fix the file.

Otherwise, look at the settings file ("%LocalAppData%/Electronic Arts/EA Desktop/user_xxx.ini) and remove the duplicate options.

Otherwise, look at the settings file ("%LocalAppData%/Electronic Arts/EA Desktop/user_xxx.ini) and remove the duplicate options.

That did the trick. The ini had two identical entries of this parameter -> deleted one -> No error.

Many thanks!
