Update VAF 23.6.687.5 vault is unstable

Hi,

I have upgrade my VAF Application with VAF  23.6.687.5. (MFilesAPI is in version 23.9.12966.6)

This project use a custom library compiled with MFilesAPI version 23.9.12966.6

The compilation and the VAF application install are correct (no error) but the MFAppPlateform stops and starts continuously.

In the event observer I have :

1-Information : coffre "CAIR_QUALIF" est en ligne. ID du coffre : {6B31CC31-CFEB-4068-ACC0-FBC8B23315B6}

2-Warning : CAIR_QUALIF ({6B31CC31-CFEB-4068-ACC0-FBC8B23315B6})
M-Files Network Folder Connector: Network Folder, P:Fournisseur (fbc66a819a1e48fea62e7864df3a5a4f): Indexing is enabled for this external repository connection but the indexer user has not been authenticated. Either authenticate the indexer user or disable indexing for this connection.

and I have no error when the VAF starts and stops.

I don't want return in version 2.2 and I need to make change for my customer, I don't know where to look

 M-Files Server is in version :23.9.12966.6

Best regards
