Renaming multiple files causes TF to lock up

TF 1.13.3 and macOS Big Sur Beta 10:

Selecting multiple files and choosing “Rename” from the context menu results in a TF Visor window that is greyed out (see screenshot, might be hard to tell that it’s greyed out) and cannot be interacted with normally. The Rename operation cannot be completed or canceled and though the Visor can still be summoned/dismissed, nothing inside the window can be clicked. The only way out of the situation is to close the Visor window (CMD-W) or to restart Finder completely.
