Additional information no error when removing the Xuse ir flag there was also a probably unrelated warning just before the error but I also had it with previous versions copied below `WARNING An illegal reflective access operation has occurred` `WARNING Illegal reflective access by com intellij util ReflectionUtil file Users emmanuel m2 repository org jetbrains kotlin kotlin compiler 1 4 31 kotlin compiler 1 4 31 jar to method java util ResourceBundle setParent java util ResourceBundle ` `WARNING Please consider reporting this to the maintainers of com intellij util ReflectionUtil` `WARNING Use illegal access=warn to enable warnings of further illegal reflective access operations` `WARNING All illegal access operations will be denied in a future release`

you could try making a copy of JpayUserRepo and delete code until it no longer fails then you know whats causing it
