I am using Julia 1.0.5 and Juno 0.3.0. My code seemingly runs fine, but after running, Julia will crash if I write anything else afterward, giving the following error message:

Exception: EXCEPTION\_ACCESS\_VIOLATION at 0x6b6496af – jl\_compile\_linfo at /home/Administrator/buildbot/worker/package\_win64/build/src/home/Administrator/buildbot/worker/package\_win64/build/src\codegen.cpp:1191  
in expression starting at no file:0

This seems to happen no matter what code I run and I do not understand why.

This is hard to debug, but is there a reason why you’re on such an old Julia and Juno version? Juno is on version `0.8.2` currently

Do you or your employer happen to have Cylance installed? If so, it’s known to kill Julia unless whitelisted. There are a few posts here on this. A workaround until whitelisting is given in [Julia blocked by CylanceUI - #11 by StefanKarpinski](https://discourse.julialang.org/t/julia-blocked-by-cylanceui/28332/11).
