While pico seems to mean “little” it’s still a lot.
Have you checked whether these apps are available via alternative sources like apk mirror or racoon?
Some apps (claim they) need Google Play Services to work, but you can install the FLOSS microG Services instead.
Google Play Services can’t be deactivated entirely.
Please check the Guide to living without Google on an FP2 to learn more and continue there if you have further questions.
My tip: Backup whatever you need, do a hard reset and start over without “open” GAPPS but microG instead.
