ER-301 Freezes on specific Slot

Hi,

For some reason it happens just with slot 10, if I load it or save a project from another slot in slot 10, then the ER-301 freezes and I can’t do anything anymore. I attach the crash log file. I have tried to delete the content of slot 10 from all the quicksaves folders (both in sc and in the firmwares folders) but it still persists, I really don’t know what do to!

Thanks in advance for helping.

Edit:
I think the problem for some reason sussists when you use the percentage “%” symbol to name a save.
