Hey -
The problem you were running into might be specific to 4.7.6", we would need extra information to reproduce - you are certainly trying to load some project and we don’t know which one. Could you retry with 4.8 and try creating a new project? But beware that as described in the linked post below by RCL, a current issue with running the engine on Arch Linux machines. In short the number of static TLS used by editor shared objects + system shared objects appears to exceed the system limit on Arch Linux.
