Error in the Subject mask

[Atara23879160o7gt]

I downloaded the latest 14 version of LRC last week. This week I imported new photos to edit, and there was constant error with the subject masks I use, that every time I 'fixed' it as the LRC asked, it came back again. 

I read in this forum that there is another update 14.0.1 that fixes it. I downloaded it also, and the problem hasn't gone. 

After a lot of tries and frustrations I downloaded back the old 13.x version, and went back to the old catalog,uploaded the photos all over again, started to edit again and still this error exist! 

I can continue working with this right now, and I have costumers waiting for their photos, and also I have my whole time dedicated to editing - I simply can't edit and do my work because of this bug! 

Please, help me and fix it!

These steps have worked for nearly everyone who has posted on the forums about this issue:

1. Update to LR 14.1.1.

2. Do the command Edit > Catalog Settings > General > Show to open File Explorer on the catalog folder.

3. Exit LR.

4. In the catalog folder, delete the file <catalog name>.lrcat-data.  Be careful not to delete anything else. This file stores information about AI masks and Generative Remove and will be recreated in the following steps.

5. Start LR.

6. In Library, select all photos, and do the menu command Photo > Develop Settings > Update AI Settings. This will recompute all the masks and Generative Removes and can take a long time. But when it's done, you shouldn't have to update AI settings again.
