FYI Episerver update 211: EPiServer.CMS.11.5.3 has dependency to EPiServer.CMS.TinyMce (≥ 2.1.1) but latest TinyMce NuGet currently is version 2.1.0
Workaround is to just ignore the EPiServer.CMS package (not update it) and update the other packages so you get the latest release 211 into use for those.
