The short answer

Install released game updates first. The publisher says version 0.1.2 fixed WD-L020 crashes linked to KB5124010. If the code remains after updating, record your current Windows build and reproduction steps rather than assuming the old cause still applies.

Step 1｜Check the fix history and update the game

The 0.1.2 notes followed the September 23 investigation and listed a fix for the Windows-update-related crash.

Time: About 5 minutes · Risk: low

  1. Exit the game and complete pending WARDOGS downloads in Steam.
  2. Do not downgrade to find 0.1.2. A later 0.2.0 release was announced on October 15; use the currently released client.
  3. Compare one launch after updating. A maintenance window announced in September is not evidence of an outage today.

Results that did not fix the problem help the next reader too.

Step 2｜General checks: restart and verify files

These checks do not establish a newly confirmed cause of WD-L020.

Time: About 10 minutes, depending on verification · Risk: low

  1. Restart Steam and Windows normally, then check whether the same code appears.
  2. If it persists, open the game’s Properties in Steam Library and verify the installed files. Wait for completion before comparing again.
  3. Record each change and result. Keep security and anti-cheat protection enabled; do not install unofficial replacement DLLs.

Results that did not fix the problem help the next reader too.

Step 3｜Record the Windows build and triggering conditions

The September 23 rollback advice was a temporary option before the fix. This guide does not instruct you to remove Windows updates.

Time: About 5 minutes · Risk: low

  1. Press Windows + R, run winver, and record the version and OS build. Note relevant Windows Update history and when the error began.
  2. Collect the game version, full error, launch steps and results of restarting or verifying files.
  3. Record WD-L014 or WD-L018 separately. Their September 30 notice says fixes were in progress; the material reviewed here does not confirm completion for those codes. This is not a new observation of an ongoing outage today.
  4. Report through official Team17 support. Review diagnostic information for private details; do not post a full DxDiag report publicly or remove a different update based on guesswork.

Results that did not fix the problem help the next reader too.

Step 4｜Treat login and server problems after launch separately

Failure to launch with WD-L020 is different from a connection failure inside the game.

Time: About 5 minutes · Risk: low

  1. If the game opens, record whether the failure is a queue, sign-in error or disconnect from a particular server. Distinguish the game closing from the whole PC restarting, and avoid repeatedly triggering either failure.
  2. Use the server guide below to check notice dates and scope, client updates, server region and filters.
  3. Historical launch congestion or an older fix does not establish that a widespread outage is continuing now.

Results that did not fix the problem help the next reader too.

Avoid

  • Do not start by removing Windows updates or disabling anti-cheat.
  • Do not delete saves or blindly overwrite cloud data.

Important cautions

  • This guide is not a hands-on test. The 0.1.2 fix applies to the documented condition; it does not guarantee every future WD-L020 error is resolved.

FAQ

Should I follow the old advice to remove KB5124010 now?

Prioritize the released game fix and evidence from your current system. A pre-fix optional workaround is not a universal instruction for current PCs.

Is a long queue also WD-L020?

If the game launches and displays a queue, use the connection guide. Choose checks based on the actual error text and where the process stops.
