Lags in Catalina 10.15.4

[REd83840]

Hello. So I updated my macOS Catalina 10.15.3 to 10.15.4. I updated my clover to r5107 and updated all the kexts. installed the update from the settings app. I selected the install data disk. it took a really long time to update and then it said macOS is not installed.
got this error message- the bless tool was unable to set the startup disk
then I booted into my main hard drive and it booted fine and showed me the version 10.15.4.
so the update was installed but its really laggy and slow. my graphics are working fine so I don't know what's the problem. it wasn't in 10.15.3.
here is the install failed log.
and the clover folder

did you list them correctly in config.plist?

did you list them correctly in config.plist?

I moved the files and run the snapshot command in propertree

you will have to make sure they are enabled

 

[REd83840]

They are there in my config.plist. How else can i check if they are enabled or not?
