Hi there!
Solutions don’t really have a versioning functionality like apps or flows. If you want to roll back to how components were in version v1.0.0.50, you have two options:
Rollback the entire environment: Roll back the whole environment to the date when you had that version. This will roll back the entire environment and all existing solutions within it. You can find more information at this link.
Use a ZIP file: If you have a ZIP file with your unmanaged solution version v1.0.0.50, you can delete the current version and import the old one.
If this helps, please mark it as the solution by clicking "Accept as solution." A "Like" would be greatly appreciated if you found the content helpful. Thanks!
Best,
