Caution the Release Candidate 2 of macOS 13.4 and possibly older versions have updated the Apple Diagnostics tool and is incorrectly reporting that there may be issues with the SD Card Reader.
If I may ask members here if they can perform a Apple Diags and report back the result along with the hardware you are using and what macOS Version is currently installed.
And with any string of luck, Apple can issue a RC3 before release or a hot fix shortly thereafter as this incorrect reporting can cause an influx of Apple Support / Genius appointments and very likely lead to unnecessary hardware replacements.
