AutoCAD DWG TrueView 2022 wont open my dxf files.

I send out all my files in "DXF 2010" format.
A client is trying to open them with AutoCAD DWG TrueView 2022 but they are getting the following error:

The following error was encountered while reading
in XRECORD starting at line 27218:
DXF read error
Invalid or incomplete DXF input -- drawing discarded.
Press ENTER to continue:

On enter press it cancels opening the drawing.

Opening the DXF file with notepad++ to line 27218 is as follows.

XRECORD
5
70
102
{ACAD_REACTORS
330
6F
102
}
330

AcDbXrecord
280

5005
bpenEnabled
290

5005
bpenFileName

sketchy.bpen

I can erase these lines and then the file will open fine, but i don't want to have to do this every time i have to send out of a file.
