Hi @Kyle Raven,
I'm not sure what's going. It seems like a browser issue because I've never had this experience before. You can attempt the regular stuff, clear cache and cookies, try in private browsing. But what you can do is capture a HAR trace file and share it so it can be investigated further.
Beyond that, you can use the Azure CLI to get around your issue and do a zip deploy. The following doc shows you how to do that; https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push#cli.
However, you still need to create the storage account that Azure function, but essentially, you would do the following:
az login
az group create --name AzureFunctionsQuickstart-rg --location <REGION>
az storage account create --name <STORAGE_NAME> --location <REGION> --resource-group AzureFunctionsQuickstart-rg --sku Standard_LRS --allow-blob-public-access false
az functionapp create --resource-group AzureFunctionsQuickstart-rg --consumption-plan-location <REGION> --runtime dotnet-isolated --functions-version 4 --name <APP_NAME> --storage-account <STORAGE_NAME>
func azure functionapp publish <APP_NAME>
