[igor-toporet]

We are experiencing this issue. Would you happen to have any insights on how to work around it?

I don't know if it matters, but we have caching enabled; I'll disable it and see if it's still reproducing.

[TwentyFourMinutes]

We are experiencing this issue as well - at least the stack trace matches for this case. For us it occurs during startup.

[xC0dex]

Could you share on which machine/OS it occurs? I thought that I fixed it with this PR #57972 (This PR introduced the failing test). I'm unable to reproduce the issue on my machine..

[TwentyFourMinutes]

@xC0dex I am currently under Windows 11 24H2 26100.4061 - though I am not quite certain yet that I am on the correct issue - My issue is not necessarily related to concurrency. Anyhow I am trying to figure what causes the issue... I'll respond again once I figured.

[TwentyFourMinutes]

@xC0dex I got it working by removing Min/Max Length attributes as well as Nullable Collections that caused a very similar stack trace. Sorry for the inconvenience, and thanks for responding that quickly.

Have a nice day
