5.21.0 has introduced a regression causing some queries to generate the error signature:
key not found: VariableSlotKey(ke)
Prefixing the affected query with runtime=legacy should provide a workaround in the short-term, while we continue to work on a fix for the issue. We expect to release a patch shortly.
Further to my post on June 28, we now have a release patch on neo4j.com that fixes two regressions in Cypher introduced in 5.21.0, and a kernel issue - see details below.
Customers upgrading to 5.21 should use this patch version. Customer who have already upgraded to 5.21.0 should patch to this release to prevent the potential for the regressions to trigger errors in Cypher.
Fixes:
Cypher
Fixed issue that could produce errors like: Neo.DatabaseError.General.UnknownError key not found: VariableSlotKey(b) for queries with ...RETURN b AS renamedB, count(b) or similar.
Fix issue that could result in error class org.neo4j.cypher.internal.physicalplanning.ast.NullCheckReferenceProperty cannot be cast to class org.neo4j.cypher.internal.expressions.ASTCachedProperty for some queries.
Kernel
This patch also fixes an issue where record IDs for any internal store in the near vicinity of 4294967295 could be invalidly marked as deleted when growing the ID space beyond that particular ID.

Expansion of the allowed index settings for the vector-2.0 vector index provider, as well as additional updates to vector similarity and dimensionality settings.
Deprecation of High Limit and Standard store formats, following the completion of the Block format rollout.
Adds a scope clause for importing variables into CALL subqueries e.g. CALL (a, b) {... }.

Added the GQL conformant OPTIONAL keyword to procedure and subquery calls. If no results are returned from the procedure or subquery, OPTIONAL CALL will return null instead of an empty result.
Allow ORDER BY, SKIP/OFFSET, and LIMIT to be standalone clauses. Before, they could be used only in combination with RETURN, WITH, or YIELD; now, they can be used anywhere in a query.
Authentication and authorization providers can now be controlled at a user-level with Cypher by setting the Auth Providers option on each user.
