Python in Excel not available
The only limitation I know Python is not supported for device-based licenses https://support.microsoft.com/en-us/office/python-in-excel-availability-781383e6-86b9-4156-84fb-93e786f7cab0
otherwise it shall be available on E5 Current channel for Excel desktop on Windows. Build number actually doesn't matter.
And it's better to repeat your question in comments to Python in Excel – Available Now
I have user-based licensing, and it's unfortunate if the answer is "at some point and for some non-public reason the features are turned on as we see fit", but I did talk to https://answers.microsoft.com/en-us/msoffice/forum/all/cannot-access-python-in-excel/129800e4-d25f-4017-bf3f-0213e39d7930?messageId=2fee560e-f93d-456d-9d87-71c2ae614771 and since I do have a premiere support contract I filed a support ticket. If I find out there is anything people in my situation can do I will update this thread here.
Looks like a bug, thank you for sharing. As workaround temporary you may shift on Current channel, that's few minutes job.
