?:0 table index is NaN

Trying to convert 4 scans from film using Canon 6d Mark ii. It converts one and then throws the error in the topic

“An internal error has occurred. ?:0: table index is NaN”

Running on Lightroom Classic v 20201001851-ef6045e0 on Mac OS 10.15.7

Hey by any chance have you figured what had happened?
