@zzdravkin I downloaded latest code from your branch and checked, it also crashed. see the attached video for a better idea.

@zzdravkin I found one more issue with the same time zone (America/Mazatlan). Here current date is 2024-02-02(YYYY-MM-dd) format and I loaded the FSCalendar with a current date but it displays January month dates instead of February months. You can check the below video please give a solution if you have one. In the video above center date is the current date.
