Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login

if this is just the update you are asking about , then Combo update macOS 10.15.4 https://support.apple.com/kb/DL2037?locale=en_US
