Running simplex-desktop-bin 7.1.0-1 gives the following error message. In fact, last two or three versions behaved the same. Basically, recent versions have been unusable. The version that ever worked was one published probably last year.

@wolfk
this is not true (about "only one fix"). I have explained nature of this crash in my comment. TL;DR: another workaround: downgrade

@matthewq337, @IAmHugh had the same SIGSEGV as @IAmHugh, this could only be fixed by setting the environment SKIKO_RENDER_API=SOFTWARE before starting simplex-desktop
