Cant mine

I was playing the combat update test and I suddenly could no longer mine anything after placing a torch on a block under me on its side. I was also having other issues such as when I was mining things that after I let go of the lmb it continued to mine. I cant progress any farther in the game due to this bug. When I left click instead of doing the intending action a sideways sword appears in the middle of the screen with a bar that fills up underneath it like in the previous combat system. It isn't a official release in the launcher I had to install it from Jeb's post on reddit here: https://www.reddit.com/r/Minecraft/comments/c5mqwv/a_custom_java_edition_snapshot_to_test_new_combat/ Edit: The issue was fixed after rebooting the launcher and opening the world again. I think it has to do with playing the combat test for prolonged periods of time.
