Launch Thunderbird daily or from trunk.
The spaces toolbar doesn't show up for up to 5 seconds.

User case https://thunderbird.topicbox.com/groups/beta/T18eaba202dc38c4b/space-bar-and-unified-toolbar-not-appearing-immediately-at-startup-in-tb-119-0b3-64-bit

After upgrade from 118.0b2 to 119.0b3 it takes 3mn+ for Space Bar and Unified Toolbar to appear at startup.

Also noticed that the Folder Header pane re-appeared while it was hidden previously and my customised button have disappeared from Unified Toolbar.

https://mozilla.github.io/mozregression/ will likely help you find the cause of your issue.
But given the significant difference in performance, I have doubts they are the same issue as Alex's

I found the regression.
https://hg.mozilla.org/comm-central/rev/15e6413835fce1499b48e7714cbdebb685345f0e

It affects beta because it was uplifted to 119.0b3
Backing those changes out fixes everything.
