2d Plan, can‘t „add“ new Page and can‘t „delete “ Layers


I run Version 4.8-1243 and Beta 4.9-1249 on a Win 11 PC, both Version with self Problem.
First: I can,t add a new Page in 2D Plan.
Second: I can‘t delete a Layer in 2D Plan.

Do i have an issue in my Brain or it‘s a Bug?

I think we have experienced something similar on 1243. On PC we could not copy a 2d plan or creat new. But on Console we could.

So I think there is something going on, but I cant provide any more information at the moment.

Could you upload your show file to Uploads? Maybe something went bad in there, and we can have a look
