migration issues

I had my minecraft java edition and windows (bedrock edition) on 2 different emails before the migration but when the migration start, i migrate my java edition to another microsoft account that i created with the old email for the java edition so now the 2 game versions are one 2 microsoft account. Before it's was fine but i just change my PC and i must download the launcher from the microsoft store and it only accept 1 of the 2 emails and when i install the java version i cant install the bedrock windows version and even uninstall and log in to the old account with minecraft bedrock version before still cant download the bedrock version. So is there a way i can like combine the 2 account or at least a way for to download both of it on my new PC?

Thank you
