The process accountsd is eating up CPU since 10.15.4

Hello everybody !

Since I updated to Catalina I've been suffering from problems with my Gmail accounts, asking frequently to reconnect them and I could not find a solution to correct it (some users said to synchronise calendar or contacts in Internet Accounts but it did not work for me). It has become worse since 10.15.4 update, they ask to connect less frequently but the process accountsd is eating up all my CPU and making my computer unusable !! I am using 10.15.4 on a MB 12" bought in february 2018 (late 2017 model).

Thanks for your help !
