I'm not a programmer but a quick Bing search shows this to be a Delphi programming error message.
RichEdit - line insertion error - embarcadero.delphi.vcl.using (codeverge.com)
The situation here that's causing the error is due to the character string being too long and the program runs out of memory.
With that said, what is the path where your asset is being edited?
Are you using C:/users/<your username>/AppData/Local/N3V Games/TRS19/build xxxxxx? (The xxxxxx = the letters and numbers.)
It maybe that the magic combination of the asset-name plus the path makes the Delphi program barf and unable to open.
The other issue could be where do you have AssetX installed?
Is it in the normal C:/Program Files (x86)/PEVs Tools/AssetX or did you put it another location with more folders?
My hunch this might be the cause.
There's an easy way to test this.
1) Put the asset opened for edit into another folder right off the root of the drive.
- Create a temp folder if you don't have one already.
- Go into Content Manager.
- Open an asset for editing.
- Open Windows File Explorer
- Open the editing folder in your TRS19 data folder.
- Copy the asset-folder.
It'll look something like this:
kuid2 425700 103730 1 CL Coaling Stage -
- Paste this folder in your temp folder.
- Start up AssetX and open the asset located in the temp folder instead. (I can't remember the exact steps because it's been years since I used it).
If it works, then this is the problem.
2) Install AssetX in another folder instead of the default such as C:/PEVS Tools/Asset X then run the program.
