It took a while to reach full production rate for the F-35. Partly because the supply chain (mostly US based because of the Buy American Act) had to come up to speed[0]. But also because there were running-changes being made to the plane, necessitating changes to the production line to accommodate them.
The F-22 production tooling is supposedly in storage at Sierra Army Depot. Why there and not at the boneyard at Davis-Monthan is an interesting question[1]. Spooling production of the F-22 back up will take less time than originally, but still won't be quick (a secure factory floor large enough has to be found, workforce knowledge has been lost, adding upgrades, etc.)

[1] I was at Sierra in the 80's on TDY and it was all Army and Army civilians. A USAF guy like me really stood out.
