Cannot open PDB automatically in OCI

Hello,

I have a 19.13 database in OCI, and i have created new PDB few weeks ago. After creation i have opened the PDB and save state. If i shutdown the CDB and start it up the PDB is opened without any problem, but when i shutdown the compute instance and after that i start it (it is automatically starting the CDB and PDBS) i get error:

ORA-00704: bootstrap process failure

ORA-28365: wallet is not open

for the newly create PDB. After few minutes i manually open the database and it opens without any problems. I have check the tablespaces and for the new PDB all tbs are encrypted including SYSTEM and SYSAUX (it was not case of older PDB's- only app tbs were encrypted). All PDB's have AUTOLOGIN set.
