Describe the Bug

I installed the lightspeed mod together with some create addons. It randomly throws errors when lodaing like this one: https://pastebin.com/RZrQAhzk. Random mods are gtting an error like kubejs, ars nouveau, create,... I contacted the lighspeed dev about this and they told me this: "I would first reach out to flywheel devs, because of these lines:
Stacktrace:
at java.util.HashMap.computeIfAbsent(HashMap.java:1221) ~[?:?] {re:mixin}
at com.jozufozu.flywheel.core.StitchedSprite.(StitchedSprite.java:24) ~[flywheel-forge-1.19.2-0.6.9-18.jar%23999!/:0.6.9-18]
They would need to use a thread safe map"
It would be great if this was fixed because lightspeed makes my game load a lot faster. Thanks in advance
