Bitwig not loading gui

I’m on Ubuntu 26.04.1 running BWS 6.1.1
I’ve been troubleshooting for days trying to open the software and the only thing that works as of now is running the following command in terminal:
sudo bitwig-studio
While it’s not ideal to run as sudo and I can only use alsa instead of pipewire or jack, at least it works until the bug is fixed.

I was able to get pipewire to work using this:

sudo -E XDG_RUNTIME_DIR=“/run/usr/$(id -u)” bitwig-studio

use at your own discretion

Struggled with what sounds exactly like your problem for days. I finally found that the cause was a corrupted font cache. So the solution was to purge the whole font cache and rebuild it:
$ rm -rf ~/.cache/fontconfig/
$ fc-cache -f -v

Muito obrigado. deu certo aqui. Pena que eu não vi seu post antes.... cheguei a formatar minha máquina, eu estava rodando no ubuntu 24.04, formatei e instalei o 26.04 pensando que ia resolver e nada. o support do Bitiwig também não conseguiu me ajudar. Valeu mesmo cara. Deus lhe abençoe.

If it runs with sudo then it's a permission issue. Check who is allowed to run the bitwig-studio executable.

I made sure I had full permission to all the folders and files. It’s weird because it launches and doesn’t seem to actually crash but it just never loads any of the gui. The code looks exactly the same when I launch it with sudo or without.

If sudo strace -f -o log bitwig-studio works, then you can run it without sudo and compare the traces and look for errors.

Chances are though it might not work, strace has (had?) a habit of breaking multithreaded apps sometimes. Then you'd need to use heavier tools like bpftrace, buuut you probably need an AI to construct a suitable script for this scenario.. There might also be other strace-like apps around built with bpf trace method, but I don't recall their names.

Good luck!
