TinyMCE after update causing errors

Hello everyone,

I have updated episerver to 11.3.3.0 and installed from nuget tinymce package EpiServer.CMS.TinyMce (version 1.0.0.0).

now everytime I want to see a page properties in the admin panel, if a page has the property of type XhtmlString, for instance (public virtual XhtmlString Footer), I am not able to see any properties at all with the error (any page that does not have such  a property XhtmlString is loading fine):

Unable to find a module by assembly 'EPiServer.DynamicContent, Version=1.0.1.0, Culture=neutral, PublicKeyToken=8fe83dea738b45b7'
Parameter name: moduleAssembly

I have verified that EpiServer.DynamicContent dll of that version is installed and actually in bin directory for the run time.

I have unistalled and installed again the tinyMce. 

Here is the log for the tinyMCE installation:
