Premiere Pro Mac Memory Issue

Hello, I'm an editor for a commercial company, and I've recently had a major memory issue with Premiere Pro Ver 25.5 on my Mac computer. I thought I had too much media on my project file when a Memory Limit pop-up appeared on my computer, and it enlisted that my project file was 108 GB. I tried making a new premiere project folder and copying over only the intended pieces of media, but the pop up came up again an hour later, even though the folder says the project is 7 MB large compared to the prior 12 MB large file. I tried clearing old media cache and allocation more RAM to Premiere (12/18 GB to 14/18 GB), and nothing changed. I didn't add any plug ins or anything that'd add memory to the project file.  I've tried most google suggestions, but nothings changes, and I'm trying to avoid getting a larger processor, is there anything else I can do to fix this?
