Just updated to the latest version of IntelliJ IDEA this week.
When I go back home after work, I put my computer in sleep mode.
In the morning after, when I wake up my computer, I find that my IntelliJ IDEA is frozen and not responding.
These are my version details:
IntelliJ IDEA 2019.1 (Ultimate Edition)
Build #IU-191.6183.87, built on March 27, 2019
JRE: 1.8.0_202-release-1483-b39 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Thanks for your help!
