Premiere Pro chugging, freezing, not playing back sequence

Hello all!

I have been having an issue with the current Premiere Pro. Previously I have had these issues but they seemed to resolve themselves quite quickly whereas now I am sitting around for 20 minutes until its able to be worked on again and even then it could only work for 5 minutes before going back to freezing.

I will load up my video, start work on editing it. Once I start skimming through the sequence and want to hit play, its as if Prem freezes. The play/Pause button changes but nothing happens. Sometimes the sequence will play but there is only a black screen with no audio.

Sometimes, the video will play for around 3 seconds and freeze but it will still play the audio.

As I said I have only run into this issue mainly in the last couple of weeks after I edited a 2 hour video. At first I thought it was due to there being a lot of resources in the sequence but I am now editing a 8 minute video with only footage and its also happening with this.

I have just ordered another 16gb of ram to try and mitigate the issue.

My current pc specs are:

AMD Ryzen 5 3600X 6-Core Processor 3.79 GHz

Nvidia GTX 1660 Super

Corsair Vengeance 16gb DDR4 3600

Windows 10

I am looking at upgrading my GPU soon also, but for the time being I'd just like to stablise the software a bit better. I know my hardware isn't the best it could be and I know that video editing does have a lot of strain on machines. I am just looking to cut down the freezes times as currently I am estimating an hour per video, but with the freezes its adding another 2 to 3 hours on top.

I am currently using version 23.3. I was using the most up to date but tried to downgrade to see if it would help. Sadly not.

I have 12gb of ram dedicated to Premiere Pro.

Any more info that ive missed, please let me know!

Thanks in advance!
