• are you using the new architecture?

NO, this is probably the reason of the error.

• which version of react & react-native are you using?

"expo": "~54.0.22"
"react": "19.1.0"
"react-native": "0.81.5"

By using 4.5.5 as before, we get SIGSV fault, so it's not an option for us.... probably because react native is too new.

@razvanphp Did you try other old-architecture versions of Slider? v4.5.6 and v4.5.7?
You didn't give any info what version are you using in this issue, but know that from v5 of Slider only the new architecture is supported.
