Cannot combine JPEG files into one PDF

Hello,

I cannot combine JPEG files into one PDF. It does combine PDFs without any problem.

It also does not convert them to PDFs if I select multiple JPEGs and hit the convert PDFs. It gives the error - the files are either not supported or corrupted.

I am using the latest version Acrobat DC (21.011.20039) (32 bit). I am using Windows 10 (64-bit).

I tried repair installation. It did not work.

I also did uninstall and reinstall it. When I launced the reinstall, in my first try, it did combine the JPEGs interestingly, but then it started giving errors in my second try.

I have another laptop which also has the acrobat installed (up-to-date). I opened it and tried it - it did not work there either..

Both computers are new, up-to-date and virus scanned. Combining JPEG feature used to work but anymore. Could be related to the recent update?

Appreciate any feedback to resolve this issue.

Thanks
