Unified Folders broke, and now I can't reactivate it

I have two email accounts: my personal Gmail and my work's Google Workspace account.

Until last week, I was using Unified Folders to view both inboxes on the same screen. However, one day, Thunderbird started showing an empty panel instead of my emails. The emails only reappeared after I used Troubleshoot Mode to reset the configuration, but that action disabled Unified Folders.

Since then, I’ve been unable to reactivate Unified Folders. When I select the option, it doesn't "stick."

I've reviewed the posts Unified folders was working fine, now it's not working. and Problem displaying unified folders and the page as well as the page Unified Folders not working, but none of the suggested solutions worked for me.

I am using Thunderbird 128.5.0esr (64-bit) on Windows 11, but also tried versions 133 and 115, and they all behaved the same way, even when creating brand-new accounts.

Opening the Developer Tools and activating the Unified Folders, the following error messages apear: I guess some of them occur because I deleted the file virtualFolders.dat and the "smart mailboxes" folder.

I restarted Thunderbird, opened the "Developer Tools" and tried to enable the Unified Folders. This is the error message that appeared.
