Basically I’ve tried a whole bunch of shit and none of it worked. Found out that Internet Explorer and Microsoft Edge aren’t loading flash properly. Internet Explorer says it’s not installed (while addons show A “Shockwave Flash Object” addon is in there, enabled with unknown publisher) and Microsoft Edge says it’s disabled despite the option very clearly being enabled in advanced options.
Flash works properly in Firefox, Chrome, and the Steam web browser. Before I discovered those two as the culprit, I’ve tried the following in regards to being able to see videos again:
1. Did a clean reinstall of flash multiple times
2. Reinstalled Gmod
3. Redownloaded awesomium
4. Made both awesomium and gmod run as admin
5. Opened ports in both Windows firewall and my router
6. Did a sfc /scannow. Detected corrupted files and fixed some but was unable to fix all of them. The log said no errors occured with flash installation.
7. Uninstalled/reinstalled both Net Framework 3.5 and Internet Explorer 11
8. Reset Internet Explorer entirely.
9. Disabled hardware acceleration in both flash settings and internet explorer.
10. Other things I can’t think of at the moment.
If anyone has any ideas that’d be great.
