Identity Authentication Problem

Hey community i have a problem in fact after enabling resource based permission i’m no longer able to see my process instances in operate also in tasklist. by inspecting the potentials causes for the problem i found the following error :

" 1. “Cannot invoke "io.camunda.tasklist.webapp.security.identity.IdentityAuthorization.getProcessesAllowedToStart()" because the return value of "io.camunda.tasklist.webapp.security.identity.IdentityAuthentication.getAuthorizations()" is null”"

so is there anyone familiar with this issue and can help me.
for info i’am using self managed camunda.
