Library versus Develop Module Color Differences

I find myself grappling with a rather frustrating issue: instead of a simple color shift, my blacks are inexplicably washing out. As a dedicated Lightroom user, I’ve attempted various approaches to resolve this conundrum. When I disable the GPU, the images appear the same in both the Develop and Library modules; however, they still look washed out, losing crucial detail. On the other hand, enabling HDR in the library module from the performance settings does provide consistency between the two modules, but unfortunately, upon opening the images in Photoshop, I encounter that same degradation in the shadow areas. This seems to be unavoidable.

I am using a Mac M2 Studio and I've taken the time to calibrate my BenQ monitor with the current Spyder tools,  and even experimented with generic calibrations to rule out any ICC profile issues, but to no avail.  Additionally, I've meticulously checked all color profiles to ensure they match perfectly. I've tried several profiles, including my standard Adobe RGB 1998, along with sRGB and ProPhoto, yet the results remain the same.

As a professional landscape photographer, I've built my business on delivering stunning prints that have consistently met my clients' expectations for over a decade. Now, however, I'm facing the unsettling challenge of images coming out flat and washed out, which is severely impacting my business. I have spent countless hours in “help” sessions with Adobe representatives, yet we've made little progress. This issue has persisted on numerous forums for years, with many citing the GPU as the potential culprit, but a solution remains elusive.

It’s high time for Adobe to address this critical issue. My business and passion for photography depend on it!

Sorry for so many self replies, but thisis pretty live action for me as I have a job I need to complete.... 

I read this thread: https://community.adobe.com/t5/lightroom-classic-discussions/big-difference-in-colors-between-the-develop-module-to-the-library-please-help/td-p/10384094 

...and tried to trun off my GPU. This worked. I have a NVIDEO GeForce RTX 4080 This is supposed to be a compatible card with Lightroom. It pains me to not be able to use it's power and asssitance. Anyone have ideas on corretion to this GPU issue beyond "turn it off"? 

If you are talking about Lightroom Classic (are you? you didn't say) then updating Camera Raw has no effect.

Color mismatch between Library and Develop could indicate a corrupted monitor profile.
