Bug description

Signal crashes on restoring a (valid) backup file. In particular when starting restoring from a file backup, messages seems to be processed and imported correctly. However afterwards, Signal crashes repeatedly on startup and cannot be started anymore, i.e. Android reports that the app is crashing repeatedly responding.

I've verified that the backup is intact with 3rd party tools (signal-backup-tools). I've also verified that the passphrase is correct; in particular I was able to extract all messages with signal-backup-tools (https://github.com/bepaald/signalbackup-tools) to text format and verified that all information is present. I've also tried to (re)write the backup using backup-tools in order to check that the backup file is not corrupted.

The database version as reported from signal-backup-tools: 136
Signal-Version: 7.2.4

The backup is from 2022; so I suspect that there is some issues when handling such "old" backups.
The backup contains personal information, but I am willing to help w.r.t. debugging this issue in any way I can

Steps to reproduce

• Install Signal from scratch from the Play Store
• Choose restore account from file backup
• Messages are processed, but afterwards Signal won't start anymore. Only wiping/re-installing Signal helkps

Actual result: Signal crashes and can't be started anymore
Expected result: Should restore the backup and start as expected

Screenshots

unfortunately I have no screenshot
