[Star Wars] After thousands of years of bureaucracy, corruption, civil wars, Sith manipulation, and gridlock during emergencies: Why did the rebellion reinstate a "new" republic after defeating the empire?

Hasn't the republic proven time and time again to be a poor system of galactic government?

The clone wars showed a massive failure:

* To act efficiently when needed in a crisis

* To root out internal corruption within the republic

* Failure to recognize manipulation by not just a sith lord, but also by the separatist systems.

* Willingly dissolved itself to put a fascist empire in place.

Even going back to the days of the old republic, the senate is still plagued by crippling bureaucracy even when faced with the Sith Empire.

when push came to shove, the republic was a terrible system of government. Why would the rebellion reinstate it after the empire was defeated? Wouldn't they worry that it would just collapse again into a new empire or something else sinister? How could such a slow plodding system possibly clean up the mess left from the empire?

"After thosuands of years"

You've answered your own question there. It had plenty of flaws, but overall the republic *worked*. It kept the galaxy going in relative stability for millennia. With the empire no longer providing stability they turned to the only other government they knew that would be able to provide it.
