Save As no longer working

I cannot use the function “Save as” I get the error message attached. I have used this before and now it has stopped working. I have shut the program and restarted and that didn’t work. Restarted the computer, checked folder permissions. Any Ideas? TIA

Have you tried saving to another folder, e.g. to the root of your C:\ drive, or to your Desktop folder? Have you tried saving with a shorter file name?

I was able to save to the desktop. I tried making the file name shorter, but that didn’t work.

I’m glad you were able to save the file in the end. If you close the project, then copy the project file from the Desktop to the folder where you tried to save it, then open it again in Dorico and then save it as normal with Ctrl+S, does that work as expected?

Yes, that worked. Was thinking of trying that later today. Odd that it wouldn’t let me save as initially.
