Inlay Hints Broken

[lishaduck]

Describe the bug

Periodically, I'll get a bunch (one per keystroke) of messages saying that "Request textDocument/inlayHint failed."
I've also noticed my computer gets really slow, and I often get this in the terminal: zsh: fork failed: resource temporarily unavailable (which I think is about memory, for which the Code Helper (...) processes spike, a Code Helper (Plugin) hits 1gb of memory used, but I can't tell which one.). Not that that's _ necessarily_ related, but they all seem to trigger about the same time, and it's Deno for which it's noticeable.

To Reproduce

No idea, beyond that it triggers randomly on this project: https://github.com/lishaduck/effect-utils.
I have yet to figure out what starts or stops it.

Expected behavior

It wouldn't do this.

(new one, didn't see this when I inspected it yesterday)
