WebView2_Child process failed ExitCode:-1073740760

After updating WebView2 to 104.0.1293.63, Cisco WebEx cannot be started.（Stuck on the WebEx login screen, spinning all the time.）
There was no problem when using WebView2 ver.100.0.1185.44 before.
What information is needed to solve this problem?

-1073740760 is STATUS_INVALID_IMAGE_HASH, suggesting that there are third party software injecting dlls into WebView renderer process.

You can use Event Viewer (eventvwr.exe) to check Error events under Microsoft-Windows-CodeIntegrity/Operational. Use the Details tab so that we can see whether an event is for msedgewebview2.exe.
As it is likely that the third party software injects into all processes, you can also attach a debugger to one of the msedgewebview2.exe process and then see which non Microsoft modules (dlls) are loaded into the process.

Once we identified the dll, try to find which third party software it is coming from and whether there is any settings in that software to exclude msedgewebview2.exe from injecting target.

If all not working, you can set environment variables WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS with value of --disable-features=RendererCodeIntegrity to disable the Edge security feature so that WebView2 can run. It is not recommended, but that would get it working.
