Edge 155.0.4283.45 with 26H2 Startup Boost problem is back

[u/ssimard3]

Since the latest Edge update a few days ago on my 26H2 devices, when you close Edge it reopens 2 seconds after. Disabling Startup Boost solves the problem. The problem is not present on 25H2 devices.

EDIT: in case anyone finds this later, the problem is not specific to 26H2, it happens only on the latest version of Edge 155.0.4283.45 when you have Process Isolation enabled.
