Can't seem to replicate this issue, so let's narrow it down.

1. How did you install this addon? (and from where)
2. Have you set to un-embed libraries?
   • Check if Wasabi is present within the libs subdirectory of BonusRollPreview.

I reinstalled and it works fine now.

I just found out that this is my fault. I try to localize the name of option panel via adding code in Options.lua cause this error:
Options.name = L['BonusRollPreview']

Thank you for your attention and sorry for this.
