hi everyone, i have succesfully managed to install freesurfer on my windows computer, with WSL2 and UBUNTU 22.04. when i open ubuntu this is what i get:

-------- freesurfer-linux-ubuntu22_x86_64-7.4.1-20230614-7eb8460 -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME /usr/local/freesurfer/7.4.1 FSFAST_HOME /usr/local/freesurfer/7.4.1/fsfast FSF_OUTPUT_FORMAT nii.gz SUBJECTS_DIR /usr/local/freesurfer/7.4.1/subjects MNI_DIR /usr/local/freesurfer/7.4.1/mni paolasofia@OR5909:~$

then when i try to launch freeview, this is what i get: paolasofia@OR5909:~$ freeview could not connect to display :0 This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, webgl, xcb.

i have installed freesurfer on my laptop following the same instructions, the ones on freesurfers website, and freeview is working fine. I searched online for suggestions and solutions but I can't seem to be able to solve the problem. i have tried it all, i am desperate. I hope somebody can help me.
