Same issue here.

This bug appears when trying to setup RetroArch as an emulator in Launchbox.

Is there any workaround please ?

I’ve not seen this one before. I would assume there is some sort of data corruption in your emulators.xml file. I would suggest you look in your backups folder and see if there is a backup you can restore that would correct this issue.
