Error on creating a project

Hello, after developing a first app within the last 12 months, meanwhile in production, all went well.
Trying to create a new project(s) for some tests, the standard project creation wizard ended up with some error msgs. Some Version conflicts, I guess (I’m not really familiar with all that config, gradle, etc. stuff). Any tips, ideas?
