Minecart closes game mid-play with error:

"Your device is almost out of the space that Minecart can use to save worlds and settings on this device."

This device has 13+GB, with another 180+GB free space on the SD card. There are many worlds (few >30MB), this is not at the world selection screen, but while playing a local single-player world (have not been playing multi-player or Realm to compare). According to the system Manage Software screen, Minecraft is only taking 1.4GB.

This happens repeatedly, kicking me to the main menu with no other warning. The only way I can reopen the saved game is by completely shutting down Minecraft and restarting (which always works... for a while). Rebooting the device did not address the issue. It appears to be happening with more frequency, after less play time in a world. Did not see this issue prior to 1.19.20.
