You're trying to translate a very large file in Trados Studio, and it throws a SystemOutOfMemory error when opening the file in Editor.
The file was created using XML V1 file types.
 

Recreate the project in Trados Studio using XML V2 file type. The new file type has improved a lot and can generate files smaller that will be processed correctly into Studio.
See the KB https://gateway.sdl.com/apex/communityknowledge?articleName=000018392 for details about how to migrate the file type.

For example, an 220MB SDLXLIFF was reduced to 55MB using the new file type and then the file was opened in Editor without issues.

There is too much information in the file to be processed correctly by Studio currently.
