ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool).slot (#452) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Variable 'ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool).slot (#452)' in ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool) (#441-459) potentially used before declaration: require(bool,string)(slot == _IMPLEMENTATION_SLOT,ERC1967Upgrade: unsupported proxiableUUID) (#453)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.
