Sometimes we use spend like "spend something on doing something" but sometimes we are using without on like "I spend a lot of time working on this project". Is there any difference between these usages? If yes, what is the difference? Thank you for your help.

In those situations, on is optional.
But use on no more than once:
- Right: I spent a lot of time working on this project.
- Right: I spent a lot of time on this project.
- Wrong: I spent a lot of time on working on this project.
Sth is not a word.

1I spent time working.... (here working is an adv.). 'I spent time on working' makes 'working' a verbal noun. Commented Mar 27, 2020 at 12:23
