Ligthroom 6.12 crash during face tag assign session

[PinoS]

I have version 6.12 of Lightroom (perpetual license) which runs on Windows 10 v. 2004 (build SO 19041.685) and I am currently managing around 30,000 photos.
Lightroom is a great product if it worked properly.
In the past I have already had problems with map management, due to Adobe's failure to adapt to the new Google Maps interface. Problems never solved.
But now the problem is more important: while assigning a face tag to a photo, Lightroom crashes.
Checking the logs I found significant elements in the AdobeIPCBroker.log file:

i couldn't find anything to fix the problem.
I also disabled the graphics processor (GeForce GTX 1050), address checks and automatic face detection.
On December 2020 this problem was not there.
But now nothing, it no longer works.

You're not on the latest available version of Lightroom 6. It's version 6.14

Take a look here: Adobe Lightroom 6 (CC 2015) Direct Download Links – Free Trials | ProDesignTools

The face detection in Lightroom 6 (even if you upgrade to 6.14) no longer works. One fix has been to set the computer's clock back to November 2020. Other than that, I don't think you will get LR 6 face detection to work. Lightroom 6 is unsupported by Adobe (and has been since 2017) and they will not fix anything that breaks.

The cause of the Face Detection problem appears to be a dll that has aged out. A dll by a third party that Adobe was using for Face Detection.

Some have found that changing their computers system clock to 12/14/18 or older gets around ths. A annoying workaround.that would have to be done each time before starting Lr.

Others simply remove the dll. However, doing that ends Face Detection.

(looking for link on community page about that dll)

Ah, dll is:

C:\Program Files\Adobe\Adobe Lightroom\CIT\Plug-ins\FaceRecognition\libfrsdk-8.6.0.dll

Identified the directory, first I renamed the DLL FaceRecognitionCognitec.dll then restored this I renamed the DLL libfrsdk-8.6.0.dll.
In both cases, activating the option "draw face areas" from the people menu, Lightroom is no longer crashed

Mind you, the Adobe response will piss you off.

Thanks.

I suspected it was related to some deadline but I also thought of something else (like: maximum number of tags managed) and I tried to activate another instance of Lightroom by loading a small subset of images and the face recognition worked.
I had also thought about regenerating the entire instance from scratch, clearly wasting a lot of time.
