I can't reproduce on fedora 37:

hugin 2022.0.0
glew 2.2.0
wxGTK-3.2.1 (but wx is built without egl support on fedora)
gtk3 3.24.36
Wayland

I compiled a debug build and added more messages. When the fast preview window is opened for the second time GLViewer::Redraw() is getting called multiple times, and hanging at SwapBuffers().

I tried testing the glFlush() above for an error, removing it (a report that SwapBuffers() does it anyway), replacing it with glFinish(). None fixed the problem.

GDK_BACKEND=x11 does workaround the problem.

Seems wxGTK still has issues to fix with Wayland.
