Files Not Uploading into Media Library

I have a few files which seemingly randomly are not uploading into Media Library. This problem only commenced in the last week or so. When I try to ‘Set Featured Image’ in the lesson, I get the following response:

Startup ‘Ukulele Tiles M2.png Post-processing of the image failed likely because the server is busy or does not have enough resources. Uploading a smaller image may help. Suggested maximum size is 2500 pixels.

The weird thing is this tile, and all of the tiles in this module are almost the same as the tiles in other modules that I can upload without problem. They are all designed in Canva, with the same layout… only the image and the text changes. They are 400×400 pixels, and I even tried compressing the png file (from 362KB down to 160KB – smaller than the tiles I could upload), and that won’t upload either.

I tried uploading under Media > add new, and get the following response (with the bar loaded to 100%):

Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.

The image is not in the Media Library, even after reloading the page.

I have another compressed pdf file (one page, 113KB) that gets the same response when I try to add it to my Media Library.

I have tried on multiple occasions at different times, and have been able to upload other files without issue, but never these ones. (Only one other pdf that compressed was under 4KB got this message one day, and then uploaded another).

I have a maximum file upload size of 512MB, so I am way under on every occasion.

I would appreciate any suggestions as I am close to being able to launch my first course, but need this resolved first! Thank you
