ConEmu Icon vanishes from task bar in Windows 11

Versions

ConEmu build: 230724 x64
OS version: Windows 11 x64 22H2 Build 22621.2428
Used shell version: powershell + cmd

Problem description

ConEmu is running with two or more console tabs open (didn't test with a single tab).

After opening some other Windows applications and switching between them, the ConEmu task bar icon vanishes.

In Process Explorer (Sysinternals) I can still see the ConEmu64.exe processes, but the "Window" submenu is grayed out.

When I run ConEmu again, a new instance is opened, which will lose it's window in the same way after some time. This may lead to quite a number of orphaned ConEmu and shell instances in Process Explorer.

Unfortunately I was not able to put my finger on the exact chain of events that triggers this behaviour - it just happens several times a day and I don't know why.

This never happened using Windows 10, it may have startet since the computer was upgraded to Windows 11 (but I am not sure if this is correlation or causation).

I know, this might be hard to reproduce. Please let me know if there is anything I can do to help narrow this down!

Steps to reproduce

1. Open Conemu.
2. Use several other applications - switch between them.
3. ConEmu main window vanishes at some point.
4. Open Process Explorer and find the ConEmu processes still running, but without a window.

Actual results

Main window vanishes.

Expected results

Main window should stay open and accessible.
