Two error names worth a row
Most Warzone error numbers in search have no official entry. This table keeps 0xe06d7363 and the generic Dev Error label, and it leaves 2029, 2030, and 2020 off because they were only autocomplete suggestions.
Error table
Fixes link to the page that actually explains them. I do not rank success rates I have not measured.
| Code | Meaning | Platform | Sources |
|---|---|---|---|
| 0xe06d7363 | Unhandled Windows C++ exception, often at launch | PC | 2 sources |
| Dev Error | Generic client fault. Sub-codes not documented | PC and consoles | 1 source — support troubleshooting is generic |
| 2029 / 2030 / 2020 | No official page found | Unknown | Autocomplete only — omitted |
The generic PC path
Activision’s PC troubleshooting article is the official ladder: verify files, update drivers, close overlays. It does not define 2029. A Steam launch crash in the Season 1 MW4 notes says to verify files and, as a last resort, reinstall after removing the Call of Duty folder. That is a launch crash, not proof it cures every Dev Error.
The detailed Windows crash is 0xe06d7363.
FAQ
What is Dev Error in Warzone?
A generic fault screen. Activision does not publish a meaning for each sub-code on the pages I checked.
What is error 2029?
I found it as a search suggestion, not as a documented code, so it is not in the fix list.
