Lightroom Classic update 18 Aug, Lens Correction Profile for Canon RF24-240

The update introduced, and set as default, a version 2 lens correction profile for the Canon RF24-240 lens which causes the Raw image to display incorrectly by showing an area outside that of the matching camera Jpeg which is  blurred and distorted (I have only found this for images shot at zooms of 38mm upwards).  This region can of course be cropped out as it is not part of the intended image.  Reversion to the previous profile removes the problem.

I can confirm this behavior with LrC 10.4 and ACR 13.4 on my Windows 10 system using the v2 lens profile. The original (v1) lens profile does not exhibit the issue.

I see it also... M1 MacBook Air.  THANK YOU for posting this.  I'm about to leave on a long trip covering an event where I will rely very heavily on this camera/lens combo.  Glad I'm learning about this now rather than after importing hundreds of images the first day.  I would have been in major panic mode.  No big deal now that I know what it is and how to correct it.

Hi Folks,

Which Canon body(ies) are you seeing this behavior with?

Thank you.

R5 for me.  I'll test later on an R and post if that helps
