MSP430FR2475: I2c Always busy

Part Number: MSP430FR2475

Hi, Busy bit in UCBxSTATW is always set after I enable I2c with "EUSCI_B_I2C_enable(EUSCI_B1_BASE);" Am i doing something wrong?

I have 10k pull up resitor on SDA and SCL , I measured them and both are high.

Also tried to send a STOP  by "HWREG16(EUSCI_B1_BASE + OFS_UCBxCTLW0) |= UCTXSTP;"
