assert failure in sapling

pivx-qt: sapling/saplingscriptpubkeyman.cpp:997:
 void SaplingScriptPubKeyMan::GetSaplingNoteWitnesses(const std::vector<SaplingOutPoint>&, std::vector<boost::optional<libzcash::IncrementalWitness<32, libzcash::PedersenHash> > >&, uint256&) const: Assertion `*rt == witnesses[i]->root()' failed.

1.Check logs:
-Look for recent chain reorganizations or errors related to Sapling notes.

2.Rebuild witness cache:
-Try re-scanning the wallet:
./pivx-qt -zapwallettxes=2
or use rescanblockchain via RPC.

3.Print roots before assert (if modifying code):
std::cout << "Expected root: " << rt->ToString() << ", witness root: " << witnesses[i]->root().ToString() << std::endl;
4.Backup wallet and test with a fresh rescan.
