Google Drive upload freezing

My flow uploads base64 files to Google Drive. It works great for files roughly below 3MB, but the upload step freezes completely for files larger than 3MB, with no error messages or anything else that might help debug the root cause.

Any thoughts on how I can make this work? I’m expecting file sizes below 100MB.

Could you provide the file details, such as mimeType and size, to help us replicate the issue? Are these base64 files fetched from the previous step or trigger?

mimeType is PDF. Size is between 3MB and 10MB (I tried multiple files - those below 3MB were successful). The files are created in a previous step (a JS code piece) and passed to the Google Drive upload piece.
