Lightroom Classic CC soft proofing bug

For the last year or so, Lightroom soft proofing on my Windows 10 laptop has stopped working. It just shows the same image regardless of the profile selected.

I've seen the bug fix that has worked for a lot of people (switch off GPU, switch off gamut indicators) but they haven't done a thing on my copy - the image doesn't change at all to reflect the proofing profile. 

To see if it's just the version on my laptop, I've gone back to install the latest version of Classic CC on my barely-functioning 2012 Macbook Air, and soft proofing works fine on that - just not on my 18-month-old Win10 HP. This is extremely frustrating, as I'm providing prints for clients and can't just keep ordering test 6x4s to check the colour.

Anyone else having this problem on Win10?

The specs:
Windows PC - i7, 8GB RAM, Lightroom Classic CC 7.5
Macbook Air 2012 - MacOS High Sierra, 4GB RAM, Lightroom Classic 7.5

Thanks for reporting this issue Andrew. Does it happen for some specific images or all images?

Thanks for getting back to me. It happens with every image, and in every catalog (I've tried exporting a couple of hundred images to a new catalog but saw no difference) - but it only happens on Windows.

Soft proofing in the same version of Lightroom Classic (7.5) still works without any problems at all on the old Mac, which makes it doubly frustrating as the Mac itself is too unreliable to use.

Recalibrate and build a new display profile and make sure it is NOT a version 4 (V4) spec but instead V2. Any difference?

Thanks for the suggestion Andrew. I don't have any calibration kit at the moment, but it's clearly worth looking into. I'd previously found that Lightroom's soft proofing was perfectly accurate from the laptop screen to test 4x6 prints, so getting  a Spyder or similar hadn't been top priority so far as most of the people I've been working with only use the files online anyway.

One thing I should note, though - none of the profiles have changed in the intervening time, it's just that Lightroom no longer previews the effect in soft proofing. Photoshop soft proofing works fine, but proofing event photos one by one with Photoshop would be a bit of a nightmare!

There has to be some display profile even if you didn’t use a product to make one. Find and delete it, reboot.

Brilliant, thanks Andrew - that seems to have done the trick. I'm still a bit puzzled by how Photoshop could read the old profile but Lightroom couldn't, but it's sorted the problem out so I'll worry about that some other time!

But it can't be the solution to delete the current monitor profile. 
I have calibrated and profiled my monitor for an accurate display. For this reason the profile must be activated and should not have any influence on the functionality of the softproof. 

In my case the softproof in Lightroom is not working. When i change the softproof profile, only the histogram is changing but not the image...
