Can't save any file in JPG or PSD

I have no ability to save files in common formats such as JPG or PNG and it's maximum weird.
"It is by design. If your file contains items that are not supported in your required format" - is NOT a solution. I can't save even the image above.
"You can "Save As" Jpeg here is how:
Step 1. Layer>Flatten Image
Step 2. File>Save As>Jpeg
Step 3. Select previous history"
Is NOT a solution too. Why I should pay for this stupid quest if I save the files through Ctrl+S during the last 20 years?
And even "The changes in Photoshop are driven by changes in the latest Mac operating system. " is the stupid solution because I use the PC.
So I have 2 questions:
1. Is there a normal way to fix it, like it was with the Scaling tool last year when Adobe damaged the UX of the most common feature? Maybe some checkbox?
2. Why Adobe doesn't respect the customers anymore?
