## TL;DR
Something went wrong in Teams is the app's generic failure screen, most often a corrupt cache or a broken install. Clear the Teams cache first; that fixes the majority. Reinstall only if the cache clear fails.

## The query
```text
how to fix "something went wrong" in the teams desktop app
```

## Use this when
- Teams desktop shows something went wrong on launch
- Teams stuck on the loading screen
- error started after an update

## Not for
- meeting audio or video problems (different troubleshooting)
- Teams web app issues (check the browser)
- sign-in errors with a specific code (look up the code)

## Steps
1. Fully quit Teams, including from the system tray. Expected output: no Teams process running
2. Clear the Teams cache folders for the app data. Expected output: cache cleared
3. Relaunch Teams and sign in again. Expected output: the app loads normally
4. If it still fails, uninstall Teams completely and install the latest version. Expected output: a clean install
5. Check the user can sign in to Teams on the web to rule out account issues. Expected output: account confirmed healthy
6. If the web app works but desktop does not, check for conflicting security software. Expected output: no blocker found
