I can't open or save a file of the tif on MacBook

Krita 4.2.8 on the Macbook OS Catalina. I can’t open or save a file of the tif(tiff) format. When I try to save or to export to the tif, or open it, I get a message: “The file format cannot be parsed”.

Known bug, or rather a build issue. It’s fixed in the nightly builds, and the fix will be in 4.2.9, which will go in beta next week.

thank you for your prompt support!
