Repro Steps
I included a link to a repo that has a test app. The methods show/Showdialog in frmMain.cs produce different bugs. To produce the bug:

1. Start the app
2. Press Button1
3. Press cntrl+f
4. without closing the find form, close frmChild
5. In this case, the error pops up when you close the main form

Hey @TheZooKeeper - thanks for the bug report, and I appreciate the repro app! I've opened this as a bug on our backlog to take a look.

[MikeCheel]

I also have users experiencing this error. Any progress or work arounds?

[champnic]

We have folks actively looking at this bug and believe we have a root cause. I'll let you know when we have a fix available to try.

[MikeCheel]

Not sure if this is part of it or not but it is being reported that setting the userDataFolder parameter to a folder inside Environment.SpecialFolder.ApplicationData (roaming user app data folder) can also cause the issues when users are on the same server using the app at the same time. They think that switching to the local application data folder will fix it. I am going to try and see if it fixes this for me.

This should be fixed in runtimes 93.0.952.0+. Thanks!

[TheZooKeeper]

Do we have a planned general release for that runtime. I see it is in the canary branch.

[champnic]

Stable WebView2 Runtime should ship version 93 around the beginning of September (around 2 weeks from now).
