Here is a working version of your presentation. The main issue was for caption package incompatibility [check this]. (search for "@SARI" word in the code below to see my comments).
\documentclass [12pt]{beamer}
% Remember you have a limited set of sizes to choose from, any unrecognised value will be considered as default. Therefore, you MUST choose from: 8pt, 9pt, 10pt, 11pt, 12pt, 14pt, 17pt, 20pt. Default 11pt in Beamer package
