What is the issue?

this has been happening for all versions of ollama for me recently (each time it updates, am hopeful it resolves this issue). some models have passed this SHA test, 2-3 but most just fail. what is causing this??

PS C:\WINDOWS\System32> ollama pull qwen3.5:9b

hi sorry i was travelling and didn't get a chance to reply before you closed it. I am running this on a Windows11 PC, i.e. i open up cmd.exe and run 'ollama pull qwen3.5:0.8b" and get the below still. How does one set GOMAXPROCS=1 on a Windows11 PC?
