Any attempt to launch ends with "Error code 1". See the attached log.

Launcher is the latest .deb from the site (1.1.26) so don't give me your "update launcher" sh*t with which you have closed a number of previous reports, it DOESN'T help.

"Java Executable" is set to "bundled runtime". Tried to clear both ~/.minecraft and separately ~/.minecraft/runtime directories, the game redownloads, but the result is the same.

1.18.2 works both with it's own bundled runtime (java-runtime-beta), and with the one from 1.19 (java-runtime-gamma) set manually.
