This proposal aims to cancel the upgrade of Polkadot Runtime to v9320, due to a change on FRAME code explained below:
As the dev team works on transforming all FRAME pallets and code to work properly with WeightsV2, they have added the following check to the scheduler pallet:
https://github.com/paritytech/substrate/blob/b1396f708b2001593d5589dd1bd3f832821fb208/frame/scheduler/src/lib.rs#L1105-L1107
This piece of code should ensure that we don't execute a scheduled call that would use more weight than we have left for the block. For most calls this isn't any problem as they should be fit easily into a block. However, for set_code the dev team currently has annotated it with using the max block weight:
https://github.com/paritytech/substrate/blob/b1396f708b2001593d5589dd1bd3f832821fb208/frame/system/src/lib.rs#L404-L405
So, when trying to execute set_code with the scheduler it will always fail this check. There will be already some consumed weight when trying to dispatch the call and some_weight + max_block_weight will always be bigger than max_block_weight. A new proposal will be submitted with the correct call soon.

Preimage is submitted.
Note this motion is an external one: meaning if/after Council approves, the community will vote on this proposal with the final decision.
