The problem doesn't occur when tested on my Chromium 106.
If you have browser extensions installed, try temporarily disabling all of
them and retest the website. If it's fine after a view tests, it means that
one of the browser extensions is interfering. Do a divide-and-conquer
strategy to pinpoint the culprit.
If still the same... press F12 to open Developer Tools panel. Switch to the
Network tab and make sure the "Disable cache" checkbox is ticked. Retest the
website. If it's fine after a view tests, it's likely that, there's a
network problem when retrieveing/re-retrieveing either the HTML or CSS
resource or both - where the data transfer of resource data was prematurely
cut. i.e. network glitch. If you're absolutely sure it only happens to your
website, then the problem is likely at the server which host your website.
In this case, contact the customer support of that server.
