Saving my images in my file BUT I cannot see the picture Photoshop 24.5 & Windows 11

I just bought a new computer with a lot more memory,  upgraded the processor ,  the rams,  everything is better.  BUT it had Windows 11 already installed on it.  Since I started working on my photos & I do a ' save as ' to save them in my files, so I can share them later on with my customers, I can no longer see the actual image, it's just a blue square with a white piece of paper in the middle & the image # is on the bottom. ( see below )  What the heck is this !!   I need to see the picture !!  Also when I click on it to open it up so I can look @ it,  it is asking me " Select an app to open the image "  Windows,  Notepad,  Media ,  and also Photoshop.  I know I'm saving the photos just like I have always done.  

WHY is it doing this ?  It has never done this to me before, to say I'm frustrated is an understatement.  I'm about to pull my hair out & it just GREW BACK !!!   If someone knows why it is doing this & how I can fix it,  I would be so grateful   THANK YOU   THANK YOU
