Upgrade failures are typically handled by @zbook, @Tekkie Boy,
and need appropriate tools to be run for log collection.
You would need time, patience, and optimism. You would also need to post the exact text of any failure message.
Just for starters:
Start with basics- check your disk (Hard Disk Sentinel, Crystal Diskinfo), then if ok run
chkdsk c: /scan
from an admin command or Powershell prompt
and if ok similarly run
SFC /SCANNOW
Before reattempting, disable or uninstall any 3rd party security software, reset any telemetry tweak tools, remove any update blockers.
Run Setupdiag.exe (free from MS) and post the result - it attempts analysis of the upgrade log files.
Post a screenshot of your partitions on all disks using a 3rd party partition manager such as Minitool Partition Wizard.
You then need specialist help from people willing to spend a lot of time on this.
Please confirm you have downloaded an iso file of your current build.
By way of an outside probability, you could try an in-place upgrade repair install of 1909 with the internet disconnected (no updates at that time).
