Macbook pro with M1 chip issue

Hi there,
I have a new MacBook Pro with chip M1 and I have found that through SketchUp Web, when I want to download a file in STL for 3D printing, it will let me download the file but apparently is ‘corrupted’. Uploading on a 3D printing webs it won’t recognise the files and shows 0.0mb file, like if it’s empty.
Instead when I download the same file through my MacBook Pro 2014 there is no issue there and the file is perfectly fine. Can I please have some advice on how to tackle this issue?
Thank you :pray:

Share the .skp file you’re working with so we can see what it is you’ve got.

What browser do you use (on the new and old)?
Which specific version?
And OS versions?
