FC Mobile Guest Account Linking Problem to Google Play

Hello, I have a Guest account in FC Mobile registered locally on my device with a GEN of 122 and named "Fenerbahçe". When I try to link this account to my Google Play Games account, a prompt to select an account appears. My Google Play Games account has an old progress of 64 GEN. I don't want my current 122 GEN Guest account to be overwritten. On the contrary, I want this 122 GEN progress to be permanently synchronized with my Google Play account. I request your help in deleting the old 64 GEN data on Google Play and linking my current 122 GEN Guest account to this Google Play account. I don't want to lose my current 122 GEN squad. When the selection screen appears, it enters a loop and freezes before I can make a selection. I wait, but the situation doesn't change, and I can't log into the game. I am attaching a screenshot of the situation. Thank you.
