Free Fire BlueStacks Guest Account Disappeared After Computer Broke

I'm reaching out about a lost Free Fire guest account that I used to play on PC through BlueStacks. The account was around level 11, and my player ID is 2603669171. I created and played on this account through BlueStacks on my old PC, but back in 2021 my computer broke down and I had to get a new one. Ever since then, I haven't been able to log back into that guest account, and at the time I never linked it to any social media or Google account. I have never reached out to support about this before.

I'm kindly asking that my guest account with ID 2603669171 be recovered and, if possible, securely linked to a Google account so I don't lose access again down the road. I'd really appreciate it if you could look into this case and let me know what additional information you need to get the account restored.
