GPU process exited unexpectedly: exit_code=34 ONLY MAUI Windows WebView2

Question

Hello IT gurus

I have a MAUI application (more platform versions) with web browser's handlers (Microsoft.Web.WebView2, Webkit.WebView, WKWebView...) all versions run OK.

But sometimes (quite ofter on my computer) ONLY on Windows platform (WebView2) I get this mysterious error and page content disapear (sometime during 5 minutes sometimes one hour..) and page shows this char: '☹'

--enable-logging shows:

[5136:17232:0430/113233.281:ERROR:fallback_task_provider.cc(126)] Every renderer should have at least one task provided by a primary task provider. If a "Renderer" fallback task is shown, it is a bug. If you have repro steps, please file a new bug and tag it as a dependency of crbug.com/739782. [5136:17232:0430/113844.288:ERROR:gpu_process_host.cc(994)] GPU process exited unexpectedly: exit_code=34 or similars..: [20260:17576:0403/183654.342:ERROR:gpu_process_host.cc(993)] GPU process exited unexpectedly: exit_code=34

After searching I tried "turn off something GPU" (--disable-gpu), but app is than EXTREMLY SLOW like 386 processore...

Do someone know, what 'GPU process exited unexpectedly' mean?

or / and

How to fix it?

thanks for ideas

best regards and nice day
