What have you done for trouble-shooting so far?

Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:

Nothing.    I just click on OK and photoshop opens with no other issues.

A hint about what you were doing when you got the message would be helpful and if you have any open application even handler enabled the would execute when Photoshop is started. What third Plug-in Photoshop would initialize. We do not know what your environment is like.

Hi John,

Sorry to hear about the program error, could you please let us know the exact version of Photoshop and operating system you're working on? You can find the exact version of Photoshop by going to Help > System Info.

To restore preferences quickly using a keyboard shortcut:
Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) as you start Photoshop.
You are prompted to delete the current settings. The new preferences files are created the next time you start Photoshop.

Note: Using the keyboard shortcut, preference files for custom shortcuts, workspaces, and color settings will also be reset to default.

For more information please check this article: Preferences in Photoshop

Please let us know how it goes.
Regards,
Sahil

I just tried Option+Command+Shift (Mac OS) when I started Photoshop, then deleted the current settings.  

The same error message came up?

When I click on OK, photoshop works with no other issues.

[c.pfaffenbichler]

What is your

Photoshop > Preferences > General > Disable the Home Screen

setting?

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?

[johndenner]

I gave it a shot, no luck.   

[Sahil.Chawla]

Could you try creating a new user for testing purpose and let us know if Photoshop works on that account?

Use menu Help>System Info and post the information here.

I have been having this issue for months and I’m super frustrate. I’ve tried everything recommended here and I’m having no luck. I get the message upon startup and if I click okay it will open but it always crashes on me after using for a bit. PLEASE HELP!!!

I'm having the same issue.

Right after starting Photoshop from the Dock, the loading splash image shows, then the error pops up:

"Could not complete the command because of a program error." After clicking OK Photoshop appears to finish loading and run normally. The error always appears when starting Photoshop again.

This is on a freshly installed system. No addons were installed. 

System Summary:

AMD Radeon HD 7950 3GB (with custom firmware)

Steps I have tried:

• Rebooting  :  same error.

• Resetting preferences (Cmd + Option + Shift when starting Photoshop) : same error.

• Disabling "Use Graphics Processor" (Preferences > Performance > Graphics Processor Settings)  :  same error.

• Uninstalling user fonts (~/Library/Fonts)  :  same error.

UPDATE: I have discovered that using the Screen Sharing app in macOS without a monitor plugged in seems to be the cause of the problem. Once I plug in a monitor the error message does not appear when starting Photoshop.

I have the same problem. Mac OS Big Sur  11.2.3, Phs CC 22.3.1, 3.2 GHz Quad-Core Intel Core i5, 32 GB 1867 MHz DDR3. I haven't done anything differently that might have triggered it, came out of nowhere. It says "Could not complete the command because of a program error." I click OK and things are fine after that, but now it's freezing after a couple of minutes work. I've done all the things suggested here, every one of them. I just updated to Photoshop 22.3.1, thinking that would fix the problem. It didn't. Driving me nuts.

[ElectroManiacal]

Is it a laptop and do you have any external monitors plugged in? I found that I got the error message when I was remoting into the computer using screenshare without a monitor plugged in. When I had a monitor plugged in, the message wouldn't appear.

[Crasch2010]

It's an iMac (Retina 5K, 27-inch, late 2015). I do have a second iMac connected as an additional display. but it's been that way for years, so I don't think it would suddenly pop up as a problem.
