Tsw4 Editor And Tsw5 Editor Not Loading Dresden Riesa, Assets Missing For My Project

I did notice the tsw4 editor has changed. When I try to open it a log shows up immediately with a list of assets failing to load.
Basically my entire dresden riesa plugin is not loading in editor even though it exists when starting the game. So my timetable project is halted since formation assets from DRA are non-existent.

Anyone else see this?

 

I’ve seen the same sort of long list of items which failed to load but not sure now if it was in relation to one particular route.
However next time I restarted the TSW4 editor there was no error list generated.

 

This also happens on tsw5 editor.
I have downloaded tsw5 and all DLC. The game works and shows Dresden Riesa in game. But the editor is not recognizing it for some reason.

 

I think I found the solution thanks to moofers#8902 posting a tip. The two editor versions are conflicting with each other and the tsw4/tsw5 content.
Uninstalled all tsw5 content and tsw5 editor. Seems like tsw4 editor is working properly again for me.

 

The same window, and my test simple route, the editor stopped seeing.

 

According to my observation, this message is not related to a specific route. I have only two German routes from the DLS in the game and shows the same editor. what to do is not clear
