Photoshop: Problems with loading a file from Lightroom

Whenever I try to edit a picture in Photoshop from Lightroom classic I get the error message that the "Extention "start" cannot be loaded because Photoshop can't find the JavaScript plugin" (I translate this from Dutch, so a similar fault in English might say it differently) When I click on "ok", the only option I have, it says: "The extension "libraries" can't be loaded because photoshop cannot find the JavaScript plugin." I then click "ok" again and get a blank screen. Normal photoshop, but without the image. 
In Lightroom, it then says that the file cannot be edited because Adobe Photoshop CC 2018 cannot be started.  I click "ok" and then nothing. Just both Lightroom and Photoshop open, but there is no picture in Photoshop. 

When I then close Photoshop it tells me that it can's save preferences because it can't find the file. I click "ok" and photoshop closes. 

After a minute or so, Lightroom tells me again that the image can't be edited because it can't find Photoshop. It then opens photoshop again en the same thing happens all over again, but now with the picture. When I click "ok" on both messages I am finally in Photoshop and I can edit the picture. I cannot, however, change my workspace to photography. When I try that it tells me that the file cannot be found. 
When I try to load a picture in Photoshop outside of Lightroom I get the same error messages, but it does load the picture the first time. I still cannot edit the workspace though. 

This problem persists even through multiple updates of both Photoshop and Lightroom. I have tried reinstalling both programs, even the entire creative cloud.

I am using the latest versions of both programs on a Windows 10 64 bit laptop with 8 gig RAM and an Intel Core i7 2.60 GHz CPU. I have an NVIDIA GeForce GTX 950M graphics card. The programs are on a Samsung mSATA SSD 500 gig (450 gig free space left) while my pictures are on a standard HDD 500 GIG (163 gig free space left). Both are inside the laptop. Both programs have run without these problems on this system, which I have for about 3 years now. 

Now I am hoping someone can help me find a solution to this problem. I like the functionality that I can open my files from Lightroom directly into photoshop and I hope that I can enjoy this in the future without this frustrating hindrance.

Hi Harm,

this reads like only having one option: Re-install Photoshop (not only update from CC-Panel).

Did you try this ?

...you would need to de-install Photoshop first, do a reboot and then install it again.

I have tried this. I completely removed Photoshop and even all Adobe products with a redownload and reïnstall.

My thoughts exactly.  Though I would be inclined to re-install both LR and PS.  The problem is likely with PS files, but if there is HDD degradation or some such, it might have affected LR as well.  I would also check your C: drive for errors before the re-install.  If you need help doing that, let us know.

My SSD is quite new (bought it last year) and the problem was there on the old one as well. I did a complete reïnstall of the programs, after removing them, thinking it might be a problem with the backup I restored. But that did not help. I have not yet seen any signs of problems with the SSD, broken clusters or anything.

I have tried to reïnstall Photoshop again today, but with no results. What i did not tell is that i cannot change my workspace to photography (or any other workspace) because files are missing. Normally you would say that a reïnstall would solve such a problem, but even a removal with all my preferences removed does not help anything. Does anyone know where these files should be located so i can check?

As noted on the other thread, I think this is a permissions issue (at least the workspace error). What is the name of the drive/volume that you have Photoshop installed on?

As stated in the other post; I did look at the permissions and made a new admin account. But that did not help. It did give me an idea though and tried running Photoshop as administrator and that did the trick. The problems where gone!! So I told windows to open photoshop always under administrator settings. Only now a photo won't open in Photoshop when I load it from Lightroom. So i put lightroom under administrator settings as well and now it works all great. So thank you for your tip!!
