Premier Pro keeps crashing

Hi adobe community, hope everyone's doing great. I recently joined this community because i need to ask a question regarding Premiere Pro as i'm running a bloging site and i need to create and edit videos according to my blogs. I was using free mobile application to edit my short vidoes but i switched to Premiere Pro as i found it very facinating and useful so i started using it but today when i was editing a video on [removed by moderator], it keeps on crashing like after every 3-4mins and i lost all of  my struggles editing the video and also all the Label Colours of Premiere Pro are changed into darker. so is it jus me or its a real bug that must have to be fixed? plus kindly suggest any alternative version that will help me for the time being. thankyou 

Regards,
