Windows 10 takes between 8 and 11 minutes to start

[Hypercubic]

My Toshiba laptop now takes between 8 and 11 minutes to start.

I am on version 21H1 (OS Build 19043.906).

I have enabled boot logging and can see many lines read "BOOTLOG_NOT_LOADED" with some text.

Parsing the log file reveals the following with the highest number of entries:

BOOTLOG_NOT_LOADED @oem9.inf,%usb3hub.drvdesc%;UoIP Hub appeared 131 times

BOOTLOG_NOT_LOADED @oem10.inf,%sensorssimulatordriver.devicedesc%;Microsoft Visual Studio Location Simulator Sensor appeared 131 times

BOOTLOG_NOT_LOADED @usbvideo.inf,%usbvideo.devicedesc%;USB Video Device appeared 9 times


Lines where the loading seemed successful specify the file name e.g.:
BOOTLOG_LOADED \SystemRoot\System32\drivers\vmci.sys


From the boot log content how can I a) identify what is actually failing to load and b) identify the reasons for it failing to load?

I have run chkdsk and it reports no errors. How do I work out what is going wrong?
