P: Most functions in Edit, Image, Layer, Select and Filter grayed out for image opened from LrC

the December 2018 upgrades to LR CC Classic and Photoshop are causing problems. When I launch PhotoShop from LR CC Classic I can't open Layers in PhotoShop. Other tabs in PhotoShop are also affected. Anyone have a fix for this problem?

Try the workarounds not in one of the full-screen modes.

When I open an image from Lightroom Classic for editing in Photoshop (Edit In > Adobe Photoshop CC 2019), I face the following issues: The menus and commands in Photoshop CC are disabled. The keyboard shortcuts don't work.

I have tried Disabling the home screen in Photoshop and opening Photoshop prior to opening Lightroom Classic CC, but this work around does not help.

Any suggestions,
Thanks,
Bruce

and some people would blithely pay more and more for a service that is getting worse and worse, and say and do nothing about it. Horses for courses. 

Photoshop cc2019 keeps crashing. or mentions not enough RAM. And when I select "edit in photoshop" from lightroom It doesn't allow me to edit. I have to have Photoshop open first and then import from lightroom It's a workaround. I love using photoshop but these last week made me regret updating. 

I hope you guys can fix some of the issues. In any case merry christmas and all that.

Since the recent update, I am not able to use shortcut keys after opening images in Photoshop from Lightroom (Edit in Photoshop menu item in Lightroom)  I also notice that many menu items in PS are grayed out. I have figured out that if I open Photoshop first or if I close my file and reopen in Photoshop it works. Will this annoying glitch be addressed in a future update?

I recently had to rebuild my PC so now I run an AMD Threadripper 1950x with lots of RAM. I’m running Windows 10 and I have the Photography package i.e. Lightroom & Photoshop. However, I have ran into some problems when I use “edit in Photoshop command” in Lightroom, Photoshop opens up as normal but if I try to do duplicate background or delete layer all the controls are greyed out, same with any of the selection menu. When I load Photoshop and then open the same files all the above controls work as expected. I have tried reinstalling without any change do I have some setting wrong or is there something else going on here.

Building frustration with Adobe.   Right now it costs more than the full master collection did, even updating it every 18 months.  Back then the update would bring way more functionality than we get per year at the moment, and far less of these showstopper bugs.   The business model works fine when you're not abusing it, but right now you are.  There are little protections in place for people who are forced into a subscription model, but that of course will change when enough people get continually shafted.  

I too had the same problem going from LR to PS.

I found a work-around as some others here did as well in that if I simply saved out the file then pulled it back in everything worked normally...

BUT  one day I forgot and I had been working on a complex selection when I went to save the selection, it was greyed out...  Oh Oh!

If I saved the PSD file and then closed it just to reopen it, I Would have lost my selection.

I read here that if you disabled the Home Page in PS it might correct the problem, so I started thinking of all things related and extrapolated a theory, and it worked for me, saving my selection and everything worked normally.

I simply undocked the working window so that it was stand alone, and that fixed it for me.

Your mileage may vary, but if it worked for me it may work for others and I thought I'd put my 2 cents in   🙂

This works. (you need also to restart Photoshop). I hope they will fix the issue asap.
