on Android 10 Minecraft version 1.16.221 when the error occurs the audio will stop while the glitch is occuring
it appears to work with any other key so long as you press that one first and continue to hold it while pressing the inventory key
this was supposed to be for Java edition I messed up really bad I don't know how to fix this help
edit:i made MC-202081 which might help...
