Working in the new Adobe Bridge 2019 today. After working a while, the screen freezes - I can move cursor, etc. however cannot open a file, make a selection, quite Bridge, etc. Only option is to Force Quite Bridge on Mac (current OS) and open again. Open the apps, make a selection and then freezes again. Done this multiple times with same affect. Can no longer continue my work. Was working OK when first installed, however no longer.
P.S. THIS IS A BUG REPORT - NOT AN IDEA AS POSTING BUTTOM IMPLIES. CLICK ON "REPORT BUGS" ON RIGH SIDE AND THIS IS THE SCREEN ONE GETS.

I have just updated my Bridge and Photoshop to their latest versions (November 2019, see detailed version info below).

**** See also update below (Bridge may now use PNGs for thumbnail/preview files in the cache for certain layered PSD files!)

It seems that there are some problems with color management in the new Bridge.
The previous version which I have used until yesterday worked OK. Nothing changed in my system except new Adobe apps today. !!Except: Updated my graphics driver just before Adobe apps (see version info below).

I use Bridge/Photoshop for photography. In Bridge the previews and thumbnails Bridge looks OK for old photos (JPEG, PSD, Raw). However, when editing old PSD files or when creating new PSD documents, the preview for the new files will (often) be wrong. What I observe is about the same effect as I get when I view photos with an application that does not support color management. Since my monitor has a wide gamut LCD panel, the difference is quite pronounced, with oversaturated colors etc.

I have done some experiments and below is a description of a procedure that in my case is able to reproduce the problem with a few simple steps.
Also, when opening a Raw file with "Open Image" in ACR (yielding a flat image in the background layer), the preview in Bridge is OK.
When opening a Raw file with "Open Object" in ACR (yielding a smart object with no background layer), the preview in Bridge is wrong.

The problem can be demonstrated like this:

1) create a new document in Photoshop (try sRGB, color managed first)
2) fill the new document with a solid color (medium bright, medium saturation, I used green)
3) save the document
4) the preview in Bridge looks OK
5) create a new document in Photoshop (try sRGB, color managed first)
6) unlock the background layer
7) make a copy of the layer (yielding two identical layers with a solid color)
8) save the document
9) *** the preview in Bridge is now wrong (it is easy to see the oversaturated color) ***

Seems to have something to do with the use of layers?

**** UPDATE: I just found out that it seems that Bridge now erroneously
generates (non-color managed) PNG files for thumbnail and preview files in the cache for certain layered PSD files!!! More info in the posts below.
Have a look at the image files in the cache file location (Windows):

C:\Users\jjoha\AppData\Roaming\Adobe\Bridge\Cache\v36

I tried turning on "Use Software Rendering" in Bridge Preferences, but it did not seem to have any effect on this problem (PNG files still made for files with wrong looking previews).

Version numbers for software/hardware used:

• Adobe Photoshop Version: Adobe Photoshop 2020 Version: 21.0.0 20191018.r.37 2019/10/18 x64
• Bridge Version: Adobe Bridge 2020: 10.0.0.124 x64
• Adobe Camera Raw Version: 12.0.0.322
• Monitor: Eizo CG2730 (calibrated regularly with Xrite i1 Display)
• Windows 10 Pro x64 version: 1903 - Os build 18362.449
• Graphics driver: Driver version: 441.12 (GeForce GTX 1060 3GB)

Just double checked turning on/off "Use Software Rendering" (with Bridge restart/PC reboot). In my case this setting does not seem to have any effect on the problem. Turning on "Use Software Rendering" just makes 100% previews slower to show up.

Also, for the files in question, Bridge still generates PNG files in its cache (which are non-color managed and are shown with oversaturated colors etc. on a wide gamut monitor), for both thumbnails, standard previews and 100% previews. As far as I can see this is new (erroneous) behavior.

Every time I launch Bridge (and, it seems, other Adobe CC apps) I get a smallish white dialog box with no information other than a circular blue progress indicator. My guess is that it is checking that it is a registered app.
I was under the impression that it only checked once every couple of months, but this happens with every launch.
In addition my Internet was down the other day and I was unable to launch Adobe apps as a result. This means that I must always be connected to the web to use my Adobe CC apps. This is surely not correct?
