The web application doesn't open my models

When I try to open any of my .skp files on the web version of Sketchup, the page turns grey and nothing opens. Most of those models are from the 2017 or 2018 Sketchup Make, some are from the 2019 web version. But whatever, they just don’t open. I went upstairs to make myself a coffee, and when I got back there was no change, still grey, still nothing opened.
I’m using Chrome on Windows 10.

How big are your models?
Have you tried using a different browser? Firefox for example.

192 Mb, I’ve opened much bigger ones before, when Sketchup Make was physically installed on my computer. Some would slow down the system. But they would work anyway.
I opened it in the CCleaner browser, which is the same as Chrome for as much as I can tell. But Now it worked. Tooke a while, but it worked.
