Error during entering Opining balances for the Fixed Assets


Our company has just started working with ERPNext for this year 2023 and during the entering of the Opining balances for the Fixed Assets we get an error whenever we try to open the Asset module, and the Chart of the Account never get affected when I ignore this error and create a new Fixed asset.
could someone please help with this error?
Thanks a lot
