Fungus or dirt in my RF 70-200 2.8?

Hello,
sorry for the "maniac" question, but while preparing my photo backpack for vacation I noticed that under the first lens of my RF 70-200 2.8 there was that element that you can see in the picture.
In your opinion is it a fungus (or the beginning of a fungus) or dirt, a hair that I think may be coming from the inside of an old backpack that I changed just because it was starting to fall apart.
Sorry, precisely, the manic question. But the last fungus (that was under the first inner lens, though) in an EF 100-400 cost me, living in Switzerland, the equivalent of $600...
Whereas if it is just dirty, of course I don't send it for control but keep it so that nothing changes....
Thank you for your opinion.
Regards

AI Data Laundering: How Academic and Nonprofit Researchers Shield Tech Companies from Accountability - Waxy.org
Tech companies working with AI are outsourcing data collection and training to academic/nonprofit research groups, shielding them from potential accountability and legal liability.

Not sure how many photographers and artists know about all these AI projects evolution and their impact on your work and IP, ownership, 3rd party usage, data scraping, etc. Ethically speaking, imho it's dubious how all of humanities creations are being chewed up into AI and spit out. Going back to the Napster days and cultural change of torrents, file sharing, etc we have a entire younger generation raised on digital everything and some of whom do not place monetary value on other peoples work and creation and find ways to copy, remix, repurpose such. It's a mixed bag, and I don't want to sound like a knuckle dragger. If you have copyrighted photos online hosted somewhere, could be likely your work has been input into this AI.
IS suddenly not working any more

Although I treat my lenses were well, the IS of my EF 35mm f/2 IS suddenly stopped working. That is very annoying, because it is the main feature of that lens. f/2 combined with IS made it a night vision lens. I wonder what is wrong with the IS. Might only the switch be broken? Without the IS I basically lose four stops now and need 16 times the ISO to compensate. That makes the lens pretty unusable for low light unless I use it on a camera with IBIS in future.
This problem damages my trust in Canon products further. Two years ago the main board of my camera broke and I had to replace it for more than 600 Euros. I found out that many people had the same problem with that camera and it might happen again with the new main board in a few years. If something like that happens, I wonder if I should invest a lot of money into an expensive Canon camera again.
I wonder how much it would cost to repair the IS. Probably more than half of the lens price and after some time it may break again, as I do not think that the replacement will have a higher quality than the original.
As cameras get more and more complex, Canon might earn a lot of money from repairs in future. We still do not know how long IBIS will last, as the first Canon cameras with IBIS came out two years ago. And what about the electronic viewfinders? How long until they break or at least have hot pixels? The camera of my grandpa still works. How long will our cameras work?
