Hello,

Just wanted to report this bug. So when I combine a bunch of pdf files I save the combined file using the "print as PDF" function (because some of the files are fillable and I want it "flattened") almost 90% of the times it won't save the file in the first attempts and it will happen in the 2nd or 3rd attempt. 5% of the time the output file only has one page(the first page out of 10-20 pages) so I have to try it again.
I am using Adobe Acrobat 2021.001.20145 on windows 10
