If you want to be able to update automatically to version 2.35 in a few weeks, update first to version 2.34.1.
The next version of the app will be divided into 6 binaries, 3 installers and 3 portables (both with x86, x64 and arm64 variants), so the update system needed to be able to handle that change.
If you keep using previous versions (v2.34 or older) and v2.35 comes out, it will suggest downloading the wrong file, so you'll need to visit www.screentogif.com to download manually the right binary.
