AE 2022 Render Get Stuck

After Effects has been giving me weird problems related to rendering for a while now but I'm finally deciding to make a post about it as this ontop of the constant crashes when Alt + Tabbing on Windows 11 have cause a huge slowdown for me the last couple of days.

 

It seems that the more I render in AE while working on a project, the slower the renders get until they eventually just either crash the program or the program gets stuck while rendering. All functions will work as normal (ex. clicking menu's (file, edit, composition) - though they're greyed out due to rendering happening, minimize and maximizing the program itself, etc.) but the actual render will just be stuck. My current render for example was stuck on 86% (Frame 17 of 22). I've tried Pause and Starting the render again with no luck, and if I click Stop it just stays the same - the render doesn't actually stop it just stays stuck. This issue forces me to end the application via Task Manager and re-do the render again.

 

To add to this, none of these renders are large/complex/time consuming. My current stuck render for example is just re-rendering a 22 frame video, no plugins/rotoscoping/fx/etc. so that I can go back in and rotoscope it without the annoying "change framerate to match sequence" issue. These renders typically take about 1-2 seconds.

 

My specs are as follows:

Nvidia RTX 3090 FE

128 GB DDR4 RAM

AMD Ryzen Threadripper 3970X

Asus ROG Zenith II Extreme Alpha

Samsung NVME SSD with the scratch disk being on a separate Samsung NVME SSD

 

Additional information that may be of use - clicking the Info button next to the render status gives the following info:

Frames per second: -3.14

Average frame time: -0.32 s

Concurrent frames rendering: 0

Start frame: 0:00:00:00

Current frame: blank

End frame: 0:00:00:21

 

RAM used: 4% of 127GB

 

I honestly have no idea what to do, but never knowing which render will be the one to freeze up AE and cause me to have to force shutdown and re-open is getting extremely frustrating especially when my system specs should allow for smooth rendering especially with simple, quick sequences like this one.

Sorry - to add to this - I just realized the actual render file itself will be finished and play fine (Just tested this with a render I just attempted). So even though AE is showing as stuck on a certain frame during rendering, the actual video output file itself is full/finished and playable.

I'm having the exact same issue, except my system resources continue to sit at 100% CPU and 100% GPU, however once it gets stuck, RAM usage drops to a level well below what is normal for rendering.

 

My info panel also reads 12 concurrent frames and it's just stuck overall but with the program fully functional as you said.

 

I'm rendering Chroma Key footage and so it can take a long while to render, so I need an indication of when it's ready as there's no way to know if and when to test the actual video file. It's strange that my system resources will remain under load even overnight when it's most likely complete if this is the case
