The game executable does not contain symbols. A DWARF symbol file is however present to recover most of it. The file is a bit broken according to these error mentions and this GitHub issue comment.

"My logic was thrown off by that very CU (the one at section offset 0x1034a5f, the 495th, zero based, in the file); its header has the abbrev table offset of 0 which doesn't make a ton of sense unless it's the very first CU; trying to parse DIEs with that offset yields bogus results. So the file, as shared by you, is malformed, and dwex can't be expected to read it properly. There was a bug that your issue has uncovered, and I will fix and publish, and this file will open, but one of the CUs will be looking bogus.

If you feel like it, go over the abbrev table by hand; maybe the abbrev table for CU 495 is physically there but the offset is off; in that case the file can be patched to correctness. But if the abbrev table for that CU is straight up absent, you are out of luck." --sevaa https://github.com/sevaa/dwex/issues/78
