Hi Gabriel, I'm Ramesh, here to answer your query at the Microsoft Community.
The two unknown entries (a random GUID string and a number) are not malicious. A game software (e.g., "Once Human" or "Almost Human") added them, but the cleanup was not done correctly.
You should be able to delete the entries via the registry or using Microsoft's Autoruns tool
Please download "Autoruns" from Microsoft, and run it as administrator:
https://learn.microsoft.com/en-us/sysinternals/...
Find the two entries shown in your screenshot and delete them.
Note:
If Autoruns doesn't see the two entries, open Task Manager and enable the two entries. Then, switch to Autoruns and click "Refresh" on the toolbar.
The entries may appear as "af_guid_xxxx" and "AF_counter_xxxx" in Autoruns or registry.
