I have re-triaged this report and can not reproduce it.
Can you please check if this is still an issue in latest build?

I can reproduce it in both the latest 2.82 Beta (Commit date: 2020-01-29 21:53, hash: c7c8ee6168) and 2.83 Alpha (Commit date: 2020-01-30 11:04, hash: 2142288eae) builds on Windows 10 64-bit Pro.

{key Tab} is leaving editmode, that is also reported here #68159 (Mesh->Normals-> Point to Target crashes when switching out of editmode)
{key Ctrl} + {key Z} will also leave editmode in certain situations (like the repro step provided here)
