I'm trying to upload a smaller demo of my project for my family to play; it isn't meant for random people. But every time I try to upload the file, I get a weird runtime error after a few minutes. When I was publishing the game, it did warn me that it's over 20 MB in size, so I compressed all of my images, which still didn't work. I have images and mp3 files for each page (it's a gamebook). I've tried on two different browsers, Chrome and Brave. Is this a common issue? Is there a fix? Is it because the images and music is too large? How can I reduce the size, if so? Thanks!

I haven't used the upload option myself yet and don't have any insight regarding that, but you could also send the compiled version using any filehosting / cloudservice you like (dropbox, onedrive, googledrive, ... ). This would also remove the limitations regarding the size and give you control over who can access this file. Your family members would need a quest client in order to play the game though.

That's the thing. Most of them can download the client, but one has a Mac, which is currently unsupported with Quest. They can deal with it, but I'd rather not leave them out.
