Bedrock Edition installation gets stuck on idle

Some background information:
-I originally owned a mojang account but had to migrate

-I originally only owned Java Edition

-I have the "old" launcher (apparently not compatible with Bedrock Edition) and the "new" launcher (apparently compatible with Bedrock Edition) installed

 

Main issues:

-When trying to install Bedrock Edition on the "new" launcher it gets stuck on idle.

-The pause and cancel buttons do not cause any reactions.

-You cannot play Java Edition while 'installing'.
