[rust-analyzer vscode plugin] Weird "Roots scanned" never finishing since today's nightly update

[StarStarJ]

I use rust-analyzer plugin preview releases and since today i get:

I doesn't progress nor does it harm the editor in any way. It's just there... forever

#15636
sounds very related

I am also pretty sure it didn't happen before, and only since today, i use vscode + rust almost daily

I've 0 plan how to debug or what could help you.
Switchting to a non-prerelease fixes it

rust-analyzer version: rust-analyzer version: 0.4.1809-standalone

rustc version: rustc 1.77.0-nightly (d78329b92 2024-01-13)

tested on 2 different machines
