After installing v3.12.3 on Linux Mint 22.3 cinnamon 64bit it wont start. When I click the icon nothing happens. I have tried both the .deb version as well as the appimage version.
I have tried it both on a Lenovo laptop as well as an HP
When running from terminal I get this:
user@computer:~$ /opt/Tempest/tempest-desktop
A JavaScript error occurred in the main process
Uncaught Exception:
Error: Cannot find module ‘undici’
Require stack:

- /opt/Tempest/resources/app.asar/out/main/index.js
