BTT quit after sleep mode

Describe the bug
Often BTT makes itself quit after computer wakes up after sleep mode.
So I don't use computer for some hours, and computer gets in sleep mode. Then I wake it up, and find that BTT icon disappear from status bar and I should start it again. This issue is pretty old, not a fresh one.

Device information:
MacMini late 2012, Mojave 10.14.5. BTT 3.02 (1159)
