Crash launcher connect microsoft account

After the migration on a microsoft account, download the correct launcher from the windows store,
it is impossible for me to connect to this new launcher neither by the microsoft account option, nor by the mojang account option.

The mojang account option launch tells me than I have already migrated my account.
The microsoft account option crash the launcher.

It is nevertheless possible for me to connect and play on the old launcher with a message asking me again to migrate to the new one
