@rseanhall I unlocked it. Looks like that happened because the bot locked it when it was closed but didn’t unlock when it was reopened. I’ll follow up with the bot owner on that behavior.
@ericstj I found what I think is the latest build from this page: https://github.com/dotnet/installer#installers-and-binaries dotnet-sdk-6.0.100-preview.3.21123.4-win-x64 Getting different errors now at least which is unrelated to this issue.
