Frequently crash on premiere while editing (windows)

Hi, I tryed find a issue like mine but I did not find. I am having frequently problems with the software crashing while I am working. A few minutes ago the message was abaout a sync failed, but for me there wasn't any problem. Today the images were made on Snapchat using the AI masks. My PC is very update, have powerfull hardwares. This kind of behaviour never happened in the past years working daily on Premiere. This could be a issue from the new version or footages from apps like TikTok or Snapchat can be the problem? From now on I will also be carefull to check if this crash happened with footages from smartphones cameras, ou even other sources of images, like HDSLR.
About my PC: Intel(R) Core(TM) i7-14700F 2.10 GHz; 32,0 GB RAM; Windows 11 Pro; Premiere Beta 24.0.

Footages from snapchat: MPEG, 1920 x 1080; frame rate: 19,59; Rec. 601 (PAL); Codec HEVC 4:2:0.

Thank you all!
