Hi there!

There is a bug when exporting to JPG but not to TIF

Lens Blur applied. One of the masks (color picker) does not work properly when exporting to JPG with lens blur ON. When either LB is off or export to TIFF, mask is working properly

LRC 13.4 on Apple Silicon

Here is catalog with DNG file with LB and a TIFF copy. In RENDER subfolder is JPG export from DNG with incorrect blue color cast on the cup

With your sample DNG, I observe slightly different misbehavior. Both exported JPEGs (sRGB) and exported TIFFs (ProPhoto 16 bit) show the incorrect blue color on the cup, but a TIFF created by doing Edit In Photoshop doesn't show the blue color. In addition, with the DNG in Develop, sometimes zooming in shows the blue color.

Note that the DNG in the catalog had AI masks that needed updating. I did Settings > Update AI Settings before doing these tests.

Tested on LR 13.4 / Mac OS 14.5 / Macbook Pro (16", 2023, M2 Max).
