Converting shape layer to frame causes layer to disappear.
On latest version 21.0.2 (Windows 10) - I've created a grid of 8 shape layers, and I'm converting them to frames to drop in images later. 5 of the shapes convert as expected. 3 of the shapes, when right-clicking the layer and choosing 'convert to frame', the shape disappears from both the canvas and from the layers panel. If I select the move tool and try to move the area the shape was around, It behaves as if it's grabbed something and the guide lines show up when I move the cursor around. Also, if I try to drop in an image to the area the frame should be, the area the frame is supposed to be highlights with a border, but dropping the image in, does not reveal anything on the canvas, the layer is still absent from the layers panel, and history shows the activity. If I undo I can revert back to the shape layer.
Converting the problem shapes to frames, saving the document and re-launching does not resolve. Rebooting the PC does not resolve. Creating a new document does not resolve but does change which shapes are problematic. The only work around I've found is to delete the shapes and re-create them. Which is tedious depending on the shapes impacted.
Putting this out there in case others experience it.
