Olympus EM1X fine line on images in PL3

I recently updated to Big Sur and note that in PL3 my Olympus EM1X RAW images have a fine vertical line around 1/3 in from the left. When exported to another application this disappears. Has anyone else encountered this phenomenon? If so, how was it resolved?

Look around for turn around but Big sure still have some issues with a lot of software. One thing many have found is with apple… dont jump too fast on the last update.
