Renderer stops working and shows black screen after some time

[link2xt]

In the console I see

Error sending from webFrameMain:  Error: Render frame was disposed before WebFrameMain could be accessed
    at WebFrameMain.send (node:electron/js2c/browser_init:2:94617)
    at WebContents.send (node:electron/js2c/browser_init:2:79767)
    at Object.send (/home/user/src/deltachat/deltachat-desktop/src/main/windows/main.ts:172:24)
    at AccountManager.<anonymous> (/home/user/src/deltachat/deltachat-desktop/src/main/deltachat/controller.ts:99:18)

Menu is still displayed, I can click File->Settings to get more errors like this.

This I select Quit and it shutdowns cleanly:

523.8s [i]main/index: Starting app shutdown process
523.8s [D]main/index: mainWindow.window.on('close')
523.9s [i]main/state: Saving state to /home/user/.config/DeltaChat/config.json
524.4s [i]main/index: Quitting now. Bye.

This is on Linux with Wayland (river wayland compositor).
