Game disconnecting me and then crashing

My wifi is fine. I used ookla speed test and got my results back with 40mbps download speed, which I think is pretty good. Then, I'm in queue , and then guess what? The game disconnects me. I think its the wifi's fault, so I go to chrome and re-load a random tab, and to my surprise, the wifi is fine. Im still not convinced that the wifi is fine, so i re-start the wifi and then send a report to my isp. So then, for a while, my league of legends started working again. Notice how i said for a while? after like 2 minutes, it started to disconnect me from the game again. This time though, after I clicked the exit thing, my game didnt exit, so i tried to force quit league. Didnt happen. It completely froze my mac, so I had to force shut down my mac. I then downloaded hextech repair tools, deleted avast and stuff like that, but my game still wasn't working. I thought that this may be a personal issue, therefore, I discorded one of my friends about it, and he said that he was doing fine. After this, I tried getting into another match after re-installing league, but the same issue repeated, so for now, ive just stopped playing league. Btw, this only started happening after 9.14, which is pretty sad, since you're supposed to be improving the clients, riot, not turning them into monkeys. Anyways, I've played games that were developed by some small company, and had no issues running it while I have problems running a client developed by an almost multi-billion dollar company. The thing that makes me mad about this though is not the problem itself, but how riot isn't at all helping the player base know about this problem or bug, or for that matter, they haven't notified us that they are trying to fix this bug. Another thing is how the league clients stability has been declining. I remember when I first joined with my other account in about 2016 that the client ran smoothly and never had problems, but after 3 years, its been getting worse. Also, at least in mac, I can only open league a certain amount of times before I have to re-start my mac to open league again, which is a pain if your game crashes because if you're unlucky, you'll have to restart the laptop, open league and load all your other apps, log in to league, and then find out that you're getting a warning for something that was the game's fault as your wifi is working great, your computer was handling league pretty smoothly, no apps were interfering with league and there wasn't any signs that league was about to crash . Anyways, this was more of a rant, so thanks for listening to this.
