3557728 - How to delete User Variant personalization that caused Corruption? Fiori Application does not load

• A user cannot open a SAP Fiori Element Application "X"
  • The user may have created a variant with custom filters and columns and saved it as a default variant
  • Since then the Fiori application does not load anymore
• Fiori Element Application does not load after user created a custom variant
• Example error:
          Error: adding element with duplicate id '<component name>::FilterBar::<filter values>'
  at onDuplicate (Element-dbg.js:218:12)
• Is there a way to delete the user created variant that may have corrupted the system for the system to load properly?
