Windows CLI2 crashes 30%+ of the time - go error?

Hey @jareda, thank you for confirming!
We are currently trying to assess the different factors that may contribute to the error that you have got.
The scale of number of items in a vault (i.e. in the hundreds) and the triggering command (i.e. op run) are so far the similarities that we encountered between the use-cases that triggered this error.
As far as I know, 1Password does not recommend any practices related to vault size, and does not impose a limit on the maximum number of items within a vault. So definitely I wouldn't call this large or an unusual number :)
We'll get back at you as soon as we have any developments related to this problem. Let us know if we can help with anything else, in the meantime!

Best,
Horia
