Is there any way to enable code highlighting? Or should we wait for an update with a fixed bug?

We've hit this issue as well. We upgraded from 3.14.4 to 3.15.1 yesterday and since then syntax highlighting is no longer working, same as @Anbu42 . Most of our dev is in Go but it appears to be happening across all languages and repos on our instance, which is a standalone appliance in Google Cloud in case that's relevant.

We have the same issue. Any ETA for the fix?

FYI for everyone asking, I was able to contact support via our GHE plan and they replied to say that there is a fix ready to go out with v3.15.2 which is currently due in January unless any issues are uncovered during testing that delay it.
