just tried sending my coins and the wallet always crash when trying.
can anybody help me?

my wallet crashes when trying to create a new receiving address or when trying to send coins.

even when trying to send coins via command line I get:

Edit:

managed to solve the error.
main solution came from this post on Gridcoin Reddit:
https://www.reddit.com/r/gridcoin/comments/adw4l9/exception_st13runtime_error_cdb_cant_open/

My .dat was corrupted, or on the way to its grave.

restarting the wallet with -salvagewallet on the shortcut solved the problem.
created a new wallet and moved all the coins

seems to be working fine now.

leaving the solution here since it canbe usefull for someone else.
