To Reproduce

Just clicking on Saved instance icon

Screenshots

Did you try having SavedInstances as the only enabled addon and everything else (especially something like ElvUI) disabled?
Don't use ELVUI, didn't try it yet.

Which version of SavedInstances are you using?
SavedInstances-10.1.1.zip

Was it working in a previous version? If yes, which was the last good one?
It was working yesterday, not working today - it was working with same version of Savedinstance.

Additional context
if i select Show instance NEVER - it start working.
