Media Encoder 2018 is disappeared from CC

Few days ago, My media encoder autonatically updated to 2019 (Which is wierd cause I close the check box to avoid automatically update.), though this cause the error since I am still using old version of AE and primere and seems the Dynamic link won't work between them
(I don't wanna update them cause some of my projects are still working)

And I couldn't find the old versions on Creative Cloud to re-install the 2018 Media Encoder CC.

I really need some suggestions to help me through this situations....
