Dual libsoup error

Upgraded Manjaro last night, now nyxt errors and hangs on startup:

libsoup-ERROR **: 15:15:18.048: libsoup2 symbols detected. Using libsoup2 and libsoup3 in the same process is not supported.

The process is there in the process table but no GUI ever appears.

I’ve re-downloaded and re-installed the Arch release build (not nightly), exact same symptoms.

That’s due to libsoup update, nothing on the Nyxt side. What I suggest you do is deleting either the libsoup or libsoup3 package, that should make errors dissappear. This may not be easy, though – as any library migration.
