Causes a freeze when I use default connected textures

[BarryMcCo]

When I start 1.21.6 with the built-in default connected textures resource pack enabled, my machine will freeze until I put it in and out of sleep mode. I don't know if it's an issue with my machine or not, but I've never had such an issue with any game before and it only happens with that resource pack enabled; disabling it causes the game to start fine.
