--- Comment #4 from Chris Caudle winehq@chriscaudle.org --- I noticed the same problem, Fedora 33 has wine 6.3 available as an update, the same installation of LTspice runs with the previous version 5.18, fails to start after updating to 6.3 (along with mingw32-wine-gecko and mingw64-wine-gecko 2.47.2).
