[ISSUE] Qt applications crash after update to qt6-wayland

https://github.com/void-linux/void-packages/issues/50953

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.94_1 x86_64 AuthenticAMD uptodate FFFFFF

### Package(s) Affected

qt6-wayland-6.6.0_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

Qt applications such as K3b or PCManFM-Qt should start without any error.

### Actual behaviour

Qt applications launched from a window manager do not run, and running them from a terminal gives an error such as `pcmanfm-qt: symbol lookup error: /usr/lib/libQt6WaylandClient.so.6: undefined symbol: _ZTIN16QNativeInterface7Private14QWaylandScreenE, version Qt_6_PRIVATE_API`

It could potentially be linked to several of the qt6 package updates but for now this is what I get.

### Steps to reproduce

1. Update qt6-wayland
2. Launch a Qt application

Comment:
It seems to be more than just `qt6-wayland`. `qt6-wayland`, `qt6-svg`, `qt6-webchannel`, and `qt6-websockets` were updated to 6.7.2_1, and this is the error now:

`pcmanfm-qt: symbol lookup error: /usr/lib/libLayerShellQtInterface.so.6: undefined symbol: _ZN15QtWaylandClient14QWaylandWindow12handleExposeERK7QRegion, version Qt_6_PRIVATE_API`

`ImportError: /usr/lib/python3.12/site-packages/PyQt6/QtCore.abi3.so: undefined symbol: _ZN14QReadWriteLock16destroyRecursiveEP21QReadWriteLockPrivate, version Qt_6_PRIVATE_API`

all matching cases online suggest towards rebuilding all qt6 apps against upstream qt6

Don't know why all comments including this one are saying resolved. Particularly this one. This is still a prominent issue.

They're queued to be rebuilt. I need to hide them to keep track of which one was processed.

PCManFM-Qt and other applications now work with the latest packages that have finished building. Will close.

Unless you're going to test all packages that requires Qt6, or rebuild all of them, no!
