Error shown while re-sizing images

Hello all,
I am new at this and I am using this software for the very first time. I am trying to resize several images, which I need for my university project. All were taken on the very same date.
I have successfully resized 60% of the images, but unfortunately, I cannot resize the remaining pictures. When I try resizing them I am met with an error.
The print screen of the error is attached below:

Resize completed with problems Image resizer was unable to resize the following picture
I don’t know where and what went wrong. If anyone can please guide me through resizing, I'll be grateful.
Is there anything I am missing in the system settings or the software settings?
Any ideas are most welcome.
Regards.
