The left side bar is missing on confluence pages for me in Chrome but it is there in Edge and in Jira. The top bar is there but spaces does not have a drop down. The Space Tools button and the collapse arrows are gone as well.
My coworkers confirmed it is still there for them but I didn't think to ask what browser they are using.
Chrome version is: Version 101.0.4951.54 (Official Build) (64-bit)

In the chrome log there is an error:
Uncaught SyntaxError: Unexpected end of input batch.js:1517
The same spot in the Edge log has the following alert:
Properties of "AJS.Confluence.QuickEdit" were over written
namespace @ batch.js?locale=en-US:509
