Your debug.log has 4 starts of Bitcoin Core v25.0.0 that all were shutdown OK.

At 2024-03-02T21:38:10Z you started Core v26.0.0 and it was able to rescan until block 623709 without issues. After that you have numerous errors like
Code:

To me it looks like your blockchain data files are corrupted from a certain point on.

And later in your debug.log there's total garbage that doesn't belong there. Didn't you notice that? Something's is severely wrong with your system (could be some issue with the filesystem or whatever caused that garbage to get dumped into the debug.log text file).
Another possibility is that the AfterRescan.log file got damaged in the process of uploading to your Google Drive, though I doubt that.

BTW, it's probably better to use pastebin.com or similar than the metadata hog Google.
