Charastudio Stuck on startup

[Hopeless_Otaku]

I've been trying to start up the charastudio for over an hour, and it's just frozen, but not unresponsive(according to task manager). It worked a few days ago, but I downloaded the latest mod updates through the manager and now it's just frozen. Does someone know if this can be fixed?

Error key if it would help:
[Error : Unity Log] ArgumentException: key already present in dictionary

Try reinstalling the latest HF patch your Studio worked fine with and refrain from updates for now.

Posting the output_log would be more helpful, but okay.

Since you wrote Studio worked fine before the mod updates: Reverse the update. If you don't have a backup: Install the HF Patch again. Either the latest or the version before. (don't forget to make a backup this time)

You want to save your userdata folder.

Noticed this happening to me too, Studio loads, but it's stuck on the loading screen. AI's studio doesn't do this, so I dunno...

EDIT: Tried it again, and apparently it works now.
