Top bar is suddenly missing

Hello,

I’m using 5.0.0-rc6 (Latest Stable Release) on linux (System Check Summary below). Everything was working fine, but after a while my top bar where I can select the date and the project I want to view went missing. After it happend the first time I reinstalled matomo to solve this issue, but now it happened the second time. I have no clue on how to reproduce this though.

In the javascript console I see:

Is there a bugfix or a workaround available?
