Gmail Calendar error - Cannot read properties of undefined

Self hosting v0.52
After recently syncing my email/calendar, When I try to go to the calendar tab an error pops up: Cannot read properties of undefined (reading 'firstName') (screenshot attached)

I dont know if i missed something in the installation or there is something else wrong.

Error logs here:
