I am wroking on a Mac Studio, macOS Monterey V12.6. I've been using LrC on this machine and others for years with no issues. Within the last month or so though, random files will be corrupted after export. They are being exported as TIFF. This may be one or two files in a batch export of 30-100 images. It doesn't happen every time I export, either.
When I try to reexport it sometimes will work and sometimes it can take 5 or 6 tries before it exports correctly. The source file is not corrupted. I couldn't find anything similar in the forums. I've had this issue on two different macs, both Mac Studios. The other Studio uses macOS Ventura V13.0. Both are using the current version of LrC v12.2.
