Describe the bug
Version 11.0.10-11-g031ea8d is not working. Getting a LUA error on startup/reload and also when trying to open the addon window.

Do you have an error log of what happened?
On login/reload:

Did you try having SavedInstances as the only enabled addon and everything else (especially something like ElvUI) disabled?
Yes. Same problem.

Which version of SavedInstances are you using?
11.0.10-11-g031ea8d

Was it working in a previous version? If yes, which was the last good one?
Yes, 11.0.10-3-gf80a966 still works.
