Previously purchased :original skyblock by Sapphire studios and skyblock bundle by Spark Squared. Due to how poor bedrock seems to be at loading since 1.16 (worsed released version ever in terms of problems) I had to install and reinstall Minecraft. Now I go to create worlds using the aforementioned templates and the load screen showing initiating comes up then it reverts to the previous menu without anything actually happening.  The below pics show the loading screen then reverting back to the previous screen.
