Chrome 84.0.4147.10 prevents Portable Apps from shutting down?

I'm using chrome 84.0.4147.10 (64-bit) on an usb stick ánd on my (work) laptop.
when running chrome from my usb stick, it prevents PortableApp Menu from shutting down? (by clicking on the X down right))
(error is a pop up "the following portable apps are stil running: chrome shut down all portable apps")
Does anyone else have this problem?
kind regards, erik jan
