Error Message: ?:0: attempt to perform arithmetic on a table value

[mwiedlin]

I've updated LR Classic 13.0.1 without issue a couple weeks ago and have processed a number of images since then. Yesterday I sucessfully processed a photo. The last thing I did was apply denoise. I then closed LR and shut down my computer. Later that day I returned to the same image in LR and found I was unable to move from the Library Module to the Development Module. A dialog box with the following message appeared upon clicking on the Development Module menu: ?:0: attempt to perform arithmetic on a table value. This error message also occurs on all images in the catalog and occurs on other catalogs as well. Any ideas on what's going on? I doubt it has anything to do with denoise, but it was the last thing that went right before the LR became nonfunctional.

I'm operating on a Windows 10, i9-10900T CPU @ 1.90 GHz, 32 GB RAM, 64-bit operating sysstem, x64-based processor.

Thanks for help!

If that last reply was what corrected your problem, then can you change what reply is correct.
