Zed: Thread "main" panicked with "Unexpected descriptor allocation error: ERROR_FRAGMENTED_POOL"

[flukejones]

Hard to say what the cause is, but it started happening in the last day where I think there was a blade update.

Caused by:
    expected value at line 1 column 1

Seems it's this Zed commit and the related blade work zed-industries/zed@08e3840

[kvark]

That's weird. We aren't fragmenting any descriptor pools ever in Blade.

Fix is coming to Zed in zed-industries/zed#12411

[flukejones]

Excellent, thanks mate.
