"Segmentation fault (core dumped)" when running in the terminal

[lelleMU]

OS:ubuntu20.04 I installed the binaries using conda following the instructions in the doc and everything worked well until I restarted my computer. After that I could not run the lpy normally. When I type conda activate lpy, that's ok. However, when I enter lpy, the lpy main window would flash and close soon with the terminal telling me: Segmentation fault (core dumped) I have no idea about what's going on...
