Hi @mjmhall1,

Any other errors? Can you please try this in an incognito window or another browser that doesn't have addons?
Take a look at the networking tab before you switch to .NET and see what happens. Generally WASM gets downloaded as needed. Something may be blocking it.

Hi Alan

Thanks for the reply. You are correct; the problem is caused by Zscaler blocking WASM.
