Blender Version
Broken: version: 3.3.1 Release Candidate, branch: master, commit date: 2022-10-03 11:17, hash: blender/blender@fb499916bb
Worked: (newest version of Blender that worked as expected)

Addon Information

Short description of error
The .wrl (VRML) File import does not correctly import the type of VRML file created by EAT's 3D Weave Tech. It opens fine in the 3D Builder app found in Microsoft Windows 10.
This has been happening since version 2.8 onwards as far as I can remember.

Exact steps for others to reproduce the error

Open Blender, delete default cube
File, Import X3D Extensible 3D (x3d/wrl)

Only a small portion of 3D model gets imported

I can confirm the error.
As the same file is imported without problem in other applications, this seems to indicate that it is valid and the error is in Blender.

To clarify, the file imports into Microsoft 3D Builder and the model is fully and correctly displayed but then reports errors and requires automatic repair.
