Sorry about the silence, lost access to the site for a bit for some reason. It still breaks. I have a feeling the purge was probably the last resort, and after formatting my drive countless times over countless issues over the last five years, I'm absolutely not doing that again if I can help it.
With my limited knowledge, I only have two ideas: It's caused by something I had installed that I can't easily test for without a VM, or it's what I've been talking about for the last two posts, the filenames affecting exclusions or whatever's happening there. I'd like to test the former, I just need to figure out how. I've briefly used a VM before to test a Linux install, but I don't think I properly understand how those work, so that might take some time. If Windows Sandbox is specifically needed, I guess I could look into upgrading from Home to Pro, but I'd like to avoid spending money if I can, on top of not knowing how much that'd cost or what it'll put on my computer.
Going back to the weird workaround I found, I just realized I was a big vague. Basically, I changed the filenames of the EXEs for Opera GX and Opera Air to match the actual names of those browsers. Normally, they're just "opera.exe" for all three of them. However, I let normal Opera keep its original EXE name. When I tested the three of them, GX worked perfectly, and so did Air, but standard Opera continued to break. They all have the exact same extensions and settings, I'm logged into them with the same account both in the browser itself and the various websites, everything is synced, and I played the same video on the same website. They also had the same tabs open for the most part, the same flags set, and basically anything else I was able to come up with. Leave no stone unturned.
Edit: Completely forgot about the errors I got when purging!
