Hi there!
A good deal is to check and install rxjs compatibility. Follows below:

npm i rxjs rxjs-compat --save

But, if it do not solve the problem for you.
You may try to downgrade you Ionic native core version.
So, in your package.json file you may change the version to something like “@ionic-native/core”: “^4.7.0” or use npm install command line.

npm install --save @ionic-native/core@4.7.0

Hope it may helps.
Have a nice time!
