Users filing ITR-5 are encountering an 'Invalid hash value' error, indicating issues with modifications made outside the utility. The common offline utility for AY 2021-22 has had problems, with Java and JSON utilities unavailable and the XML version buggy. A new JSON version (DU-.v.1.0.2) has now been released under the 'ITR 5' download tab, which may resolve these technical glitches.

Read the instruction on E-filling site ..... "Common Offline Utility for filing Income-tax Returns ITR 5, ITR 6 and ITR 7 for the AY 2021-22. Utility is enabled for ITR 7. For ITR 5 & 6, separate utility is available under ITR 5 & 6 tab as applicable."
Under ITR 5, neither Java nor Jason utility available. While XML utility is full of bugs. Hence, such technical glitch.
